Beta Pictoris (β Pic, β Pictoris) is the second brightest star in the constellation Pictor. It is located 63.4 light years from the Solar System, and is 1.75 times as massive and 8.7 times as luminous as the Sun. The Beta Pictoris system is very young, only 8–20 million years old, although it is already in the main sequence stage of its evolution. Beta Pictoris is the title member of the Beta Pictoris moving group, an association of young stars which share the same motion through space and have the same age.
Beta Pictoris shows an excess of infrared emission compared to normal stars of its type, which is caused by large quantities of dust and gas (including carbon monoxide) near the star. Detailed observations reveal a large disk of dust and gas orbiting the star, which was the first debris disk to be imaged around another star. In addition to the presence of several planetesimal belts and cometary activity, there are indications that planets have formed within this disk and that the processes of planet formation may still be ongoing. Material from the Beta Pictoris debris disk is thought to be the dominant source of interstellar meteoroids in the Solar System.
Beta (UK /ˈbiːtə/ or US /ˈbeɪtə/; uppercase Β, lowercase β, or cursive ϐ; Ancient Greek: βῆτα bḗta or Modern Greek: βήτα víta) is the second letter of the Greek alphabet. In Ancient Greek, beta represented the voiced bilabial plosive /b/. In Modern Greek, it represents the voiced labiodental fricative /v/. Letters that arose from beta include the Roman letter ⟨B⟩ and the Cyrillic letters ⟨Б⟩ and ⟨В⟩.
Like the names of most other Greek letters, the name of beta was adopted from the acrophonic name of the corresponding letter in Phoenician, which was the common Semitic word *bayt ('house'). In Greek, the name was βῆτα bêta, pronounced [bɛ̂ːta] in Ancient Greek. It is spelled βήτα in modern monotonic orthography, and pronounced [ˈvita]. In US English, the name is pronounced /ˈbeɪtə/, while in British English it is pronounced /ˈbiːtə/.
The letter beta was derived from the Phoenician letter beth .
The letter Β had the largest number of highly divergent local forms. Besides the standard form (either rounded or pointed, ), there were forms as varied as
(Gortyn),
and
(Thera),
(Argos),
(Melos),
(Corinth),
(Megara, Byzantium),
(Cyclades).
Beta Pictoris b is an exoplanet located approximately 63 light-years away in the constellation of Pictor, orbiting the 4th magnitude debris disk star Beta Pictoris. It has a mass between 4 and 11 Jupiter masses and a radius around 65% larger than Jupiter's. It orbits at 9 AU from Beta Pictoris (close to the plane of the debris disk orbiting the star) with a low eccentricity and a period of 20–21 years, and is the only known planet in the Beta Pictoris system. The planet was discovered on November 18, 2008 by Lagrange et al., using the NACO instrument on the Very Large Telescope at Cerro Paranal in northern Chile. This planet was discovered using the direct imaging technique, utilizing reference star differential imaging. The discovery image was taken in 2003, but the planet was not detected when the data were first reduced. A re-reduction of the data in 2008 using modern image processing tools revealed the faint point source now known to be a planet.
Follow-up observations performed in late 2009 and early 2010 using the same instrument recovered and confirmed the planet, but on the opposite side of the star. These findings were published in the journal Science and represented the closest orbiting planet to its star ever imaged. Observations performed in late 2010 and early 2011 allowed scientists to establish an inclination angle of the planet's orbit of 88.5 degrees, nearly edge-on. The location of the planet was found to be approximately 3.5 to 4 degrees tilted from the main disk in this system, indicating that the planet is aligned with the warped inner disk in the Beta Pictoris system.

Beta Pictoris B is the first Exoplanet ever discovered. And now, we have actual professional Astronomer video of it's movement over time. Now I did say "Professional Astronomer" So don't get your hopes up too high. To me Beta Pic B is the Hercolubus of Exoplanets. It is the Nemesis to the Beta Pictoris star. The Tyche of it's own solar system. And! That System appears to have a Tiamat like asteroid belt that has just formed, but filled with comets instead. Crazy! I know. The Article comes from David Dickinson of Universe Today http://www.universetoday.com/122479/watch-this-amazing-video-of-an-exoplanet-in-motion/ Crazy days, indeed.

Beta Pictoris remains the only directly imaged debris disk that has a giant planet (discovered in 2009) with an orbital period short enough (estimated to be between 18 and 22 years) that astronomers can see large motion in just a few years. This allows scientists to study how the Beta Pictoris disk is distorted by the presence of a massive planet embedded within the disk. Please join +Tony Darnell, Dr. +Carol Christian and +Scott Lewis as they discuss new visible-light Hubble images that traces the disk in closer to the star to within about 650 million miles of the star with the astronomers who made the observations.

For the first time, astronomers have been able to directly follow the motion of an exoplanet as it moves to the other side of its host star. The planet has the smallest orbit so far of all directly imaged exoplanets, lying as close to its host star as Saturn is to the Sun. Scientists believe that it may have formed in a similar way to the giant planets in the Solar System. This discovery proves that gas giant planets can form within discs in only a few million years, a short time in cosmic terms. Credit: ESO
This sequence starts with a broad view of the southern sky and closes in on the bright star Beta Pictoris in the constellation of Pictor (The Artist's Easel). This young star is surrounded by a dusty disc and also orbited by a large planet that is the first exoplanet to have had its spin measured. It has an equatorial rotation velocity of almost 100 000 kilometres/hour — much faster than any of the planets in the Solar System.

Beta Pictoris is a star 63 light-years away Beta Pictoris is a star located 63 light-years away. It’s estimated to be 21 million years old, or less than 1 percent the age of our solar system. Circling the star is a planet, called Beta Pictoris b, which passes vertically through the star’s bright disk of dust and debris twice each orbit. Since the disk’s discovery, astronomers have struggled to explain various features seen in images, including a warp in its center. To help find an answer, NASA scientists created a supercomputer model of the planetary system and simulated its evolution over time. The model reveals that the planet's motion drives spiral waves throughout the disk, a phenomenon that causes collisions among the orbiting debris and shapes it into the kinds of patterns seen by te...

The Gemini Planet Imager (GPI) is a dedicated facility for directly imaging and spectroscopically characterizing extrasolar planets. It combines a very high-order adaptive optics system, a diffraction-suppressing coronagraph, and an integral field spectrograph with low spectral resolution but high spatial resolution. GPI has been tuned for maximum sensitivity to faint planets near bright stars. During first light observations, we achieved an estimated H band Strehl ratio of 0.89 and a 5-sigma contrast of 106 at 0.75 arcseconds and 105 at 0.35 arcseconds. Observations of Beta Pictoris clearly detect the planet, Beta Pictoris b, in a single 60-second exposure with minimal post-processing. Fitting the Keplerian orbit of Beta Pic b using the new position together with previous astrometry gives...

Se denomina planeta extrasolar o exoplaneta a un planeta que orbita una estrella diferente al Sol y que, por tanto, no pertenece al sistema solar. Los planetas extrasolares se convirtieron en objeto de investigación científica en el siglo XX. Muchos astrónomos suponían su existencia, pero carecían de medios para identificarlos. La primera detección confirmada se hizo en 1992, con el descubrimiento de varios planetas de masa terrestre orbitando el púlsar Lich.1 La primera detección confirmada de un planeta extrasolar orbitando alrededor de una estrella de la secuencia principal (Dimidio), se hizo en 1995 por los astrónomos Michel Mayor y Didier Queloz.2 Desde entonces el número de hallazgos ha crecido año tras año.

SETI Talks Archive: http://seti.org/talks Advances in high-contrast imaging have produced a new sample of spatially resolved debris disks with morphologies attributed to the dynamical effects of planets. I will briefly review several cases, including our recent non-detection of Beta Pictoris b using Keck adaptive optics at L-prime. Then I will focus on the case for a planetary system around the nearby A star Fomalhaut. Optical coronagraphic observations using the Advanced Camera for Surveys aboard HST shows a vast dusty debris belt offset from the star and cleanly sculpted at its inside border. Follow-up HST images have further revealed a co-moving point source with apparent orbital motion 18 AU interior to the dust belt. I will discuss both the observational and theoretical eviden...
