An illustration of the Perseus constellation (after Perseus from Greek mythology) from the star catalogue published by the German astronomer Johannes Hevelius in 1690

A star catalogue, or star catalog, is an astronomical catalogue that lists stars. In astronomy, many stars are referred to simply by catalogue numbers. There are a great many different star catalogues which have been produced for different purposes over the years, and this article covers only some of the more frequently quoted ones. Star catalogues were compiled by many different ancient peoples, including the Babylonians, Greeks, Chinese, Persians and Arabs. Most modern catalogues are available in electronic format and can be freely downloaded from NASA's Astronomical Data Center.

Completeness and accuracy is described by the weakest apparent magnitude V (largest number) and the accuracy of the positions.

Historical catalogues[link]

Ancient Near East[link]

From their existing records, it is known that the ancient Egyptians recorded the names of only a few identifiable constellations and a list of thirty-six decans that were used as a star clock.^[1] The Egyptians called the circumpolar star 'the star that cannot perish' and, although they made no known formal star catalogues, they nonetheless created extensive star charts of the night sky which adorn the coffins and ceilings of tomb chambers.^[2]

Although the ancient Sumerians were the first to record the names of constellations on clay tablets,^[3] the earliest known star catalogues were compiled by the ancient Babylonians of Mesopotamia in the late 2nd millennium BC, during the Kassite Period (ca. 1531 BC to ca. 1155 BC). They are better known by their Assyrian-era name 'Three Stars Each'. These star catalogues, written on clay tablets, listed thirty-six stars: twelve for 'Anu' along the celestial equator, twelve for 'Ea' south of that, and twelve for 'Enlil' to the north.^[4] The Mul.Apin lists, dated to sometime before the Neo-Babylonian Empire (626-539 BC),^[5] are direct textual descendants of the 'Three Stars Each' lists and their constellation patterns show similarities to those of later Greek civilization.^[6]

Hellenistic world and Roman Empire[link]

In Ancient Greece, the astronomer and mathematician Eudoxus laid down a full set of the classical constellations around 370 BC.^[7] His catalogue Phaenomena, rewritten by Aratus of Soli between 275 and 250 BC as a didactic poem, became one of the most consulted astronomical texts in antiquity and beyond.^[7] It contains descriptions of the positions of the stars, the shapes of the constellations and provided information on their relative times of rising and setting.^[7]

Approximately in the 3rd century BC, the Greek astronomers Timocharis of Alexandria and Aristillus created another star catalogue. Hipparchus (c. 190 – c. 120 BC) completed his star catalogue in 129 BC,^[8] which he compared to Timocharis' and discovered that the longitude of the stars had changed over time. This led him to determine the first value of the precession of the equinoxes.^[9] In the 2nd century, Ptolemy (c. 90 - c. 186 AD) of Roman Egypt published a star catalogue as part of his Almagest, which listed 1,022 stars visible from Alexandria.^[10] Ptolemy's catalogue was based almost entirely on an earlier one by Hipparchus (Newton 1977; Rawlins 1982). It remained the standard star catalogue in the Western and Arab worlds for over eight centuries. The Islamic astronomer al-Sufi updated it in 964, and the star positions were redetermined by Ulugh Beg in 1437,^[11] but it was not fully superseded until the appearance of the thousand-star catalogue of Tycho Brahe in 1598.^[12]

Although the ancient Vedas of India specified how the ecliptic was to be divided into twenty-eight nakshatra, Indian constellation patterns were ultimately borrowed from Greek ones sometime after Alexander's conquests in Asia in the 4th century BC.^[13]

Ancient China[link]

The earliest known inscriptions for Chinese star names were written on oracle bones and date to the Shang Dynasty (c. 1600 - c. 1050 BC).^[14] Sources dating from the Zhou Dynasty (c. 1050 - 256 BC) which provide star names include the Zuo Zhuan, the Shi Jing, and the "Canon of Yao" (堯典) in the Book of Documents.^[15] The Lüshi Chunqiu written by the Qin statesman Lü Buwei (d. 235 BC) provides most of the names for the twenty-eight mansions (i.e. asterisms across the ecliptic belt of the celestial sphere used for constructing the calendar). An earlier lacquerware chest found in the Tomb of Marquis Yi of Zeng (interred in 433 BC) contains a complete list of the names of the twenty-eight mansions.^[16] Star catalogues are traditionally attributed to Shi Shen and Gan De, two rather obscure Chinese astronomers who may have been active in the 4th century BC of the Warring States Period (403-221 BC).^[17] The Shi Shen astronomy (石申天文, Shi Shen tienwen) is attributed to Shi Shen, and the Astronomic star observation (天文星占, Tianwen xingzhan) to Gan De.^[18]

It was not until the Han Dynasty (202 BC - 220 AD) that astronomers started to observe and record names for all the stars that were apparent (to the naked eye) in the night sky, not just those around the ecliptic.^[19] A star catalogue is featured in one of the chapters of the late 2nd-century-BC history work Records of the Grand Historian by Sima Qian (145-86 BC) and contains the "schools" of Shi Shen and Gan De's work (i.e. the different constellations they allegedly focused on for astrological purposes).^[20] Sima's catalogue—the Book of Celestial Offices (天官書 Tianguan shu)—includes some 90 constellations, the stars therein named after temples, ideas in philosophy, locations such as markets and shops, and different people such as farmers and soldiers.^[21] For his Spiritual Constitution of the Universe (靈憲, Ling Xian) of 120 AD, the astronomer Zhang Heng (78-139 AD) compiled a star catalogue comprising 124 constellations.^[22] Chinese constellation names were later adopted by the Koreans and Japanese.^[23]

Islamic world[link]

A large number of star catalogues were published by Muslim astronomers in the medieval Islamic world. These were mainly Zij treatises, including Arzachel's Tables of Toledo (1087), the Maragheh observatory's Zij-i Ilkhani (1272) and Ulugh Beg's Zij-i-Sultani (1437). Other famous Arabic star catalogues include Alfraganus' A compendium of the science of stars (850) which corrected Ptolemy's Almagest;^[24] and Azophi's Book of Fixed Stars (964) which described observations of the stars, their positions, magnitudes, brightness and colour, drawings for each constellation, and the first descriptions of Andromeda Galaxy^[25] and the Large Magellanic Cloud.^[26][27] Many stars are still known by their Arabic names (see List of Arabic star names).

Pre-Columbian Americas[link]

The Motul Dictionary, compiled in the 16th century by an anonymous author (although attributed to Fray Antonio de Ciudad Real), contains a list of stars originally observed by the ancient Mayas. The Maya Paris Codex also contain symbols for different constellations which were represented by mythological beings.^[28]

Bayer and Flamsteed catalogues[link]

Two systems introduced in historical catalogues remain in use to the present day. The first system comes from the German astronomer Johann Bayer's (1572–1625) Uranometria published in 1603 and is for bright stars. These are given a Greek letter followed by the genitive case of the constellation in which they are located; examples are Alpha Centauri or Gamma Cygni. The major problem with Bayer's naming system was the number of letters in the Greek alphabet (24). It was easy to run out of letters before running out of stars needing names, particularly for large constellations such as Argo Navis. Bayer extended his lists up to 67 stars by using lower-case Roman letters ("a" through "z") then upper-case ones ("A" through "Q"). Few of those designations have survived. It is worth mentioning, however, as it served as the starting point for variable star designations, which start with "R" through "Z", then "RR", "RS", "RT"..."RZ", "SS", "ST"..."ZZ" and beyond.

The second system comes from the English astronomer John Flamsteed's (1646–1719) Historia coelestis Britannica. It kept the genitive-of-the-constellation rule for the back end of his catalog names, but used numbers instead of the Greek alphabet for the front half. Examples include 61 Cygni and 47 Ursae Majoris.

Full-sky catalogues[link]

Bayer and Flamsteed covered only a few thousand stars between them. In theory, full-sky catalogues try to list every star in the sky. There are, however, literally hundreds of millions, even billions of stars resolvable by telescopes, so this is an impossible goal; these kind of catalogs generally try to get every star brighter than a given magnitude.

LAL[link]

Jérôme Lalande published the Histoire Céleste Française in 1801, which contained an extensive star catalog, among other things. The observations made were made from the Paris Observatory and so it describes mostly northern stars. This catalog contained the positions and magnitudes of 47,390 stars, out to magnitude 9, and was the most complete catalog up to that time. A significant reworking of this catalog in 1846 added reference numbers to the stars that are used to refer to some of these stars to this day. The decent accuracy of this catalog kept it in common use as a reference by observatories around the world throughout the 19th century.

HD/HDE[link]

The Henry Draper Catalogue was published in the period 1918–1924. It covers the whole sky down to about ninth or tenth magnitude, and is notable as the first large-scale attempt to catalogue spectral types of stars. The catalogue was compiled by Annie Jump Cannon and her co-workers at Harvard College Observatory under the supervision of Edward Charles Pickering, and was named in honour of Henry Draper, whose widow donated the money required to finance it.

HD numbers are widely used today for stars which have no Bayer or Flamsteed designation. Stars numbered 1–225300 are from the original catalogue and are numbered in order of right ascension for the 1900.0 epoch. Stars in the range 225301–359083 are from the 1949 extension of the catalogue. The notation HDE can be used for stars in this extension, but they are usually denoted HD as the numbering ensures that there can be no ambiguity.

SAO[link]

The Smithsonian Astrophysical Observatory catalogue was compiled in 1966 from various previous astrometric catalogues, and contains only the stars to about ninth magnitude for which accurate proper motions were known. There is considerable overlap with the Henry Draper catalogue, but any star lacking motion data is omitted. The epoch for the position measurements in the latest edition is J2000.0. The SAO catalogue contains this major piece of information not in Draper, the proper motion of the stars, so it is often used when that fact is of importance. The cross-references with the Draper and Durchmusterung catalogue numbers in the latest edition are also useful.

Names in the SAO catalogue start with the letters SAO, followed by a number. The numbers are assigned following 18 ten-degree bands in the sky, with stars sorted by right ascension within each band. One of the first stars in the SAO catalogue to be named after someone is SAO#13268 - Calaunan, Named after Rio Therese Calaunan Capistrano.

BD/CD/CPD[link]

The Bonner Durchmusterung (German: Bonn sampling) and follow-ups were the most complete of the pre-photographic star catalogues.

The Bonner Durchmusterung itself was published by Friedrich Wilhelm Argelander, Adalbert Krüger, and Eduard Schönfeld between 1852 and 1859. It covered 320,000 stars in epoch 1855.0.

As it covered only the northern sky and some of the south (being compiled from the Bonn observatory), this was then supplemented by the Südliche Durchmusterung (SD), which covers stars between declinations -1 and -23 degrees (1886, 120,000 stars). It was further supplemented by the Cordoba Durchmusterung (580,000 stars), which began to be compiled at Córdoba, Argentina in 1892 under the initiative of John M. Thome and covers declinations -22 to -90. Lastly, the Cape Photographic Durchmusterung (450,000 stars, 1896), compiled at the Cape, South Africa, covers declinations -18 to -90.

Astronomers preferentially use the HD designation of a star, as that catalogue also gives spectroscopic information, but as the Durchmusterungs cover more stars they occasionally fall back on the older designations when dealing with one not found in Draper. Unfortunately, a lot of catalogues cross-reference the Durchmusterungs without specifying which one is used in the zones of overlap, so some confusion often remains.

Star names from these catalogues include the initials of which of the four catalogues they are from (though the Southern follows the example of the Bonner and uses BD; CPD is often shortened to CP), followed by the angle of declination of the star (rounded towards zero, and thus ranging from +00 to +89 and -00 to -89), followed by an arbitrary number as there are always thousands of stars at each angle. Examples include BD+50°1725 or CD-45°13677.

AC[link]

The Catalogue astrographique (Astrographic Catalogue) was part of the international Carte du Ciel programme designed to photograph and measure the positions of all stars brighter than magnitude 11.0. In total, over 4.6 million stars were observed, many as faint as 13th magnitude. This project was started in the late 19th century. The observations were made between 1891 and 1950. To observe the entire celestial sphere without burdening too many institutions, the sky was divided among 20 observatories, by declination zones. Each observatory exposed and measured the plates of its zone, using a standardized telescope (a "normal astrograph") so each plate photographed had a similar scale of approximately 60 arcsecs/mm. The U.S. Naval Observatory took over custody of the catalogue, now in its 2000.2 edition.

USNO-B1.0[link]

USNO-B1.0 is an all-sky catalog created by research and operations astrophysicists at the U.S. Naval Observatory (as developed at the United States Naval Observatory Flagstaff Station), that presents positions, proper motions, magnitudes in various optical passbands, and star/galaxy estimators for 1,042,618,261 objects derived from 3,643,201,733 separate observations. The data was obtained from scans of 7,435 Schmidt plates taken for the various sky surveys during the last 50 years. USNO-B1.0 is believed to provide all-sky coverage, completeness down to V = 21, 0.2 arcsecond astrometric accuracy at J2000.0, 0.3 magnitude photometric accuracy in up to five colors, and 85% accuracy for distinguishing stars from non-stellar objects. USNO-B is now followed by NOMAD;^[29] both can be found on the Naval Observatory server.^[30] The Naval Observatory is currently working on B2 and C variants of the USNO catalog series.

GSC[link]

The Guide Star Catalog is an online catalog of stars produced for the purpose of accurately positioning and identifying stars satisfactory for use as guide stars by the Hubble Space Telescope program. The first version of the catalog was produced in the late 1980s by digitizing photographic plates and contained about 20 million stars, out to about magnitude 15. The latest version of this catalog contains information for 945,592,683 stars, out to magnitude 21. The latest version continues to be used to accurately position the Hubble Space Telescope.

Specialized catalogues[link]

Specialized catalogs make no effort to list all the stars in the sky, working instead to highlight a particular type of star, such as variables or nearby stars.

ADS[link]

Aitken's double star catalogue

New general catalogue of double stars within 120 deg of the North Pole (1932, R. G. Aitken).

This lists 17,180 double stars north of declination -30 degrees.

BS, BSC, HR[link]

First published in 1930 as the Yale Catalog of Bright Stars, this catalog contained information on all stars brighter than visual magnitude 6.5 in the Harvard Revised Photometry Catalogue. The list was revised in 1983 with the publication of a supplement that listed additional stars down to magnitude 7.1. The catalog detailed each star's coordinates, proper motions, photometric data, spectral types, and other useful information.

The last printed version of the Bright Star Catalogue was the 4th revised edition, released in 1982. The 5th edition is in electronic form and is available online.

Carbon Stars[link]

Stephenson's General Catalogue of galactic Carbon stars^[31] is a catalogue of 7000+ ^[32] carbon stars.

Gl, GJ, Wo[link]

The Gliese (later Gliese-Jahreiß) catalogue attempts to list all star systems within 20 parsecs (65 ly) of Earth ordered by right ascension (see the List of nearest stars). Later editions expanded the coverage to 25 parsecs (82 ly). Numbers in the range 1.0–915.0 (Gl numbers) are from the second edition, which was

Catalogue of Nearby Stars (1969, W. Gliese).

The integers up to 915 represent systems which were in the first edition. Numbers with a decimal point were used to insert new star systems for the second edition without destroying the desired order (by right ascension). This catalogue is referred to as CNS2, although this name is never used in catalogue numbers.

Numbers in the range 9001–9850 (Wo numbers) are from the supplement

Extension of the Gliese catalogue (1970, R. Woolley, E. A. Epps, M. J. Penston and S. B. Pocock).

Numbers in the ranges 1000–1294 and 2001–2159 (GJ numbers) are from the supplement

Nearby Star Data Published 1969–1978 (1979, W. Gliese and H. Jahreiß).

The range 1000–1294 represents nearby stars, while 2001–2159 represents suspected nearby stars. In the literature, the GJ numbers are sometimes retroactively extended to the Gl numbers (since there is no overlap). For example, Gliese 436 can be interchangeably referred to as either Gl 436 or GJ 436.

Numbers in the range 3001–4388 are from

Preliminary Version of the Third Catalogue of Nearby Stars (1991, W. Gliese and H. Jahreiß).

Although this version of the catalogue was termed "preliminary", it is still the current one as of March 2006^[update], and is referred to as CNS3. It lists a total of 3,803 stars. Most of these stars already had GJ numbers, but there were also 1,388 which were not numbered. The need to give these 1,388 some name has resulted in them being numbered 3001–4388 (NN numbers, for "no name"), and data files of this catalogue now usually include these numbers. An example of a star which is often referred to by one of these unofficial GJ numbers is GJ 3021.

GCTP[link]

The General Catalogue of Trigonometric Parallaxes, first published in 1952 and later superseded by the New GCTP (now in its fourth edition), covers nearly 9,000 stars. Unlike the Gliese, it does not cut off at a given distance from the Sun; rather it attempts to catalogue all known measured parallaxes. It gives the co-ordinates in 1900 epoch, the secular variation, the proper motion, the weighted average absolute parallax and its standard error, the number of parallax observations, quality of interagreement of the different values, the visual magnitude and various cross-identifications with other catalogues. Auxiliary information, including UBV photometry, MK spectral types, data on the variability and binary nature of the stars, orbits when available, and miscellaneous information to aid in determining the reliability of the data are also listed.

William F. van Altena, John Truen-liang Lee and Ellen Dorrit Hoffleit, Yale University Observatory, 1995.

HIP[link]

The Hipparcos catalogue was compiled from the data gathered by the European Space Agency's astrometric satellite Hipparcos, which was operational from 1989 to 1993. The catalogue was published in June 1997 and contains 118,218 stars; an updated version with re-processed data was published in 2007. It is particularly notable for its parallax measurements, which are considerably more accurate than those produced by ground-based observations. See Stellar parallax and List of stars in the Hipparcos Catalogue.

PPM[link]

The PPM Star Catalogue is one of best,^{[says who?]} both in the proper motion and star position till 1999. Not as precise as Hipparcos catalogue but with many more stars. The PPM was built from BD, SAO, HD and more, with sophisticated algorithm and is an extension for the Fifth Fundamental Catalogue, "Catalogues of Fundamental Stars".

Proper motion catalogues[link]

A common way of detecting nearby stars is to look for relatively high proper motions. Several catalogues exist, of which we'll mention a few. The Ross and Wolf catalogues pioneered the domain:

Ross, Frank Elmore, New Proper Motion Stars, eight successive lists, The Astronomical Journal, Vol. 36 to 48, 1925-1939^[33]

Wolf, Max, "Katalog von 1053 stärker bewegten Fixsternen", Veröff. d. Badischen Sternwarte zu Heidelberg (Königstuhl), Bd. 7, No. 10, 1919; and numerous lists in Astronomische Nachrichten, 209 to 236, 1919-1929^[34]

Willem Jacob Luyten later produced a series of catalogues:

L - Luyten, Proper motion stars and White dwarfs

Luyten, W. J., Proper Motion Survey with the forty-eight inch Schmidt Telescope, University of Minnesota, 1941 (General Catalogue of the Bruce Proper-Motion Survey)

LFT - Luyten Five-Tenths catalogue

Luyten, W. J., Proper Motion Survey with the 48 inch Schmidt Telescope, University of Minnesota, 1963-1981

Around the same time period, Henry Lee Giclas worked on a similar series of catalogs:

Giclas, H. L., et al., Lowell Proper Motion Survey, Lowell Observatory Bulletin, 1971-1979 ([9])

uvby98[link]

The ubvyβ Photoelectric Photometric Catalogue is a compilation of previously published photometric data. Published in 1998, the catalogue includes 63,316 stars surveyed through 1996.^[35]

Successors to USNO-A, USNO-B, NOMAD, UCAC and Others[link]

Stars evolve and move over time, making catalogs evolving, impermanent databases at even the most rigorous levels of production. The USNO catalogs are the most current and widely used astrometric catalogs available at present, and include USNO products such as USNO-B (the successor to USNO-A), NOMAD, UCAC and others in production or narrowly released. Some users may see specialized catalogs (more recent versions of the above), tailored catalogs, Interferometrically-produced cataloges, dynamic catalogs, and those with updated positions, motions, colors, and improved errors. Catalog data is continually collected at the Naval Observatory dark-sky facility, NOFS; and the latest refined, updated catalogs are reduced and produced by NOFS and the USNO. See the USNO Catalog and Image Servers for more information and access.^[36][37]

Claudine Margaret Castelo Barretto-Santiago (born July 20, 1979), popularly known as Claudine Barretto, is a multi-awarded film and television actress,The First and Original TELESERYE Queen, and product endorser in the Philippines.

Television roles[link]

In 1992, she was discovered by talent manager Douglas Quijano, when her older sister Gretchen Barretto brought her to the debut party of friend Ruffa Gutierrez at the Coconut Palace. That same year, she got her break on television when she was cast in ABS-CBN's youth-oriented musical variety show, Ang TV.

When Home Along Da Riles was launched with no other than the comedy king Dolphy top billing the sitcom, Claudine was casted as Dolphy's sweet and unassuming teenage daughter, Bing, for sitcom producers saw in her a potential Maria. After which, she again became part of another top-rated sitcom Oki Doki Doc, led by Aga Muhlach, where she played the sister of Agot Isidro, Toni.

Claudine also did a telemovie together with Aga Muhlach titled Kailan Mo Ako Mamahalin?.

She practiced her hosting skills through variety shows, ASAP and MTB.

By 1993, Claudine already has 12 fans club in Metro Manila. Members are high school students like her.

Claudine was first in the history of Philippine television to star in 3 consecutive soap operas. Mula Sa Puso, which brought her to stardom, starring as the rich heiress Via, opposite the late Rico Yan; next was the two-year running Saan Ka Man Naroroon, where her performance as triplets Rosario, Rosenda and Rosemarie earned her a nomination for Best Actress in the Asian TV Awards in Singapore.^[1] And Sa Dulo Ng Walang Hanggan where she played the strong-willed yet revengeful Angeline Montenegro (Angelina in the past and Angeline in the present) who is in constant battle against the villains in her life who rejoices to see her fall and continues to hinder her to be with her one, true love.

After three consecutive soap operas, Barretto became part of the ensemble cast of 2003's two-season weekly series Buttercup. In 2004, she returned to primetime via the first modern fantaserye as the mermaid who is in search of the answer to the curse that was given to her by the sea deity Victoria, Marina. 2005's Ikaw ang Lahat sa Akin where she played the role of Nea Fontanilla. A fighter, who keeps her dignity intact, who is brimming with generosity and full of positive attitude. This was the first time that she was not directed by Wenn Deramas.

After getting married, Barretto was reunited with Deramas in 2007's Walang Kapalit, where she played the role of Melanie Borromeo, the young stepsister of Noel. She has always wanted an older brother to protect her, but ended up with Noel, who seems to harbor an inexplicable hate towards her. She tends to get hurt easily, but will also put a good fight when challenged. Her life changes forever when she unexpectedly falls in love with Noel.

After giving birth, she played the role originated by Susan Roces in the 20-episode sineserye Maligno in 2008. She was Angela Cortez, a well-known newscaster, who was chosen to give birth to a demon child and although she tries to escape it, destiny catches up with her who then realizes that her son is doomed to become a satanic cult's chosen one.. This was followed by Iisa Pa Lamang, a love story that showed us the real meaning of love. She played Catherine Ramirez, an oppressed provincial girl who lost her one true love in the hands of a scheming woman. Heart-broken, homeless and rejected, Catherine strived to build a new life. Soon, blessings and opportunities come for Catherine; she then becomes a complex woman with complex values and intentions. But Catherine realizes that in order to break free from the past, she must find it in her heart to forget and forgive... before she can truly attain the happiness and true love that eluded her all these years.

Her last appearance on ABS-CBN was a special guest role in 2009's May Bukas Pa.

Upon her move to GMA 7, she was signed to star in a drama anthology entitled Claudine, which premiered on April 10, 2010.

Aside from her sitcoms and teleseryes, Claudine also did some other shows such as Star Drama Theater, Wansapanataym, Flames, Buttercup, Komiks, Star Magic Presents and Your Song.

Film career[link]

Claudine is not only reigning in television shows, but in movies as well. At a young age, she already starred with veteran actors Dolphy and Aga Muhlach, and actresses such as the Star for All Seasons Vilma Santos, Diamond Star Maricel Soriano, and Megastar Sharon Cuneta.

Claudine was Seiko's bet for stardom. Her first three films under Seiko were Kumusta Ka, Aking Mahal?, Taong Gubat and Pulis Patola. She was paired with the dashing and debonair newcomer Emil Benedicto. She also did Kung Sakali Man and God...Save the Babies under this film outfit. Although an exclusive Seiko contract star before, she was still allowed to accept two assignments with Star Cinema, Home Along da Riles da Movie and May Minamahal.

In 1994's Lagalag: The Eddie Fernandez Story, she was cast as Pops Fernandez. In 1996, she appeared in May Nagmamahal Sa'yo and Sharon Cuneta in Madrasta.

Claudine starred in more than thirty movies. In 1998, she landed her first major lead role in Dahil Mahal Na Mahal Kita where she played the role of Mela, with a reputation of a bad girl in the campus and is going steady with Mr. Bad Boy. She then meets Mr. Perfect who does not care about her. Challenged, she pursued Mr. Perfect who eventually learned to love her despite her reputation. Claudine was very convincing in this role, a true versatile actress.

In 1999, she starred in the movie version of Mula Sa Puso, and in Soltera.

In 2000, she appeared in the film Anak. Claudine played a very challenging role as Carla, a daughter who ran loose and wild for lack of guidance. Claudine received a lot or praises from this movie and people started naming her as the next Vilma Santos.

In 2001, she played a nun in Oops! Teka Lang...Diskarte Ko 'To with Robin Padilla. This was her first action film.

In 2002, Barretto received her first Box Office Queen for Got 2 Believe Where she played the role of Toni, a wedding coordinator who believes in true love and is in search of finding Mr. Right. In this movie, Claudine showed that she could not only play dramatic roles but comedic roles as well. and Kailangan Kita^[2] where she played Lena, a daughter who forgoes her personal happiness to keep her family from falling apart.

For 2004's Milan where she played the role of Jenny (an imposing figure in the Filipino community of migrant workers, whose dreams of grandeur have clouded her need for personal relationships), Barretto received the Ms. RP Movies recognition and Best Actress awards from FAP and FAMAS ^[3] beating the likes of Maricel Soriano, Nora Aunor and Judy Ann Santos. Claudine attended the red carpet screening and was overjoyed by the appreciation shown by the people all over the world.

Barretto garnered three more Best Actress awards from PASADO, FAMAS, and PMPC for 2005's Nasaan Ka Man. In this movie, we can see a very different Claudine. Pilar was difficult to portray because according to Claudine it was something new. She never played a role like it before and was at first, scared on whether she can act the role right or not.

She received a Maria Clara Best Actress trophy for her performance in Dubai.^[4] In 2007, Barretto received her second Box Office Queen crown (shared with co-star Kris Aquino) for the filmSukob where she played the role of Diana, who, together with her sister Sandy is in search of the answer to the uncanny and terrible events that happened in their lives. This movie became the highest-grossing Philippines-produced movie, a rank which it held until 2009.

Other movies include Sige, Ihataw Mo, Eat All You Can, May Minamahal, Muntik na Kitang Minahal, Mangarap Ka, Pare Ko, Radio Romance, Oki Dok Doc (The Movie), Home Along da Riles 2, Calvento Files (The Movie), and Flames the Movie.

Education[link]

Claudine attended high school at South Merville in Paranaque. She wanted to take Speech and Theater at the University of the Philippines to better herself in acting.

Claudine is someone you could call a natural performer. At age 4, she could sing an entire song complete with lyrics. Her interest in acting found expression when, at 5 years old, she would cry in front of the mirror after watching movies of Sharon Cuneta, Maricel Soriano and Vilma Santos.

The young actress started appearing in stage plays while undergoing a workshop with Repertory Philippines in 1992. Claudine was Repertory Philippines' answer to Olivia Newton John in the musical Grease.

Tulfo-Santiago NAIA Controversy[link]

On May 6, 2012, Raymart Santiago, along with Claudine and his 8 man entourage, assaulted a known journalist and senior citizen, Ramon Tulfo, due to Ramon purportedly using his mobile phone to take photos of Claudine screaming at and humiliating a ground attendant of Cebu Pacific concerning missing luggage which supposedly contained asthma medicine for their friend's children. This occurred within NAIA Terminal 3 in a location not covered by CCTV. Witnesses state that the brawl began when Raymart and his entourage surrounded Ramon and demanded that he hand over his phone. Ramon refused and the assault commenced.

A video of the brawl was recorded and posted on Youtube which clearly shows Raymart choking Ramon while encouraging his friends to throw punches at him. Claudine can clearly be seen attacking Ramon as well. The security guards eventually stop the attack and escorts Ramon away while Raymart follows alongside screaming obscenities at Ramon.

A few days after the incident, Claudine files assault and child abuse charges on Ramon as they claim that he (Ramon Tulfo) initiated the attack. Claudine also states that she has a witness to her claim. The name of the witness was not given and he has not given his account of the incident to anybody but Claudine. The rationale behind the child abuse charges, according to Claudine, comes from the fact(?) that Ramon (allegedly) begins the assault in front of her children, traumatizing them.

Upon questioning the ground attendant Claudine was heckling, she stated that it was her husband and entourage who had initiated the assault.
