Omicron Andromedae

Omicron Andromedae (ο And, ο Andromedae) is a star system in the constellation Andromeda. It is approximately 692 light years from Earth.

Omicron Andromedae is a binary star, whose two components are both spectroscopic binaries themselves, making a four-star system. The system as a whole is classified as a blue-white B-type giant with a mean combined apparent magnitude of +3.62.

The separation of the two brightest components, ο Andromedae A and ο Andromedae B, is 0.34 arcseconds. They have an orbital period of 68.6 years. A is separated from its spectroscopic companion by 0.05 arcseconds. A is a Gamma Cassiopeiae type variable star and the system's brightness varies from magnitude +3.58 to +3.78. This, in turn, has made determination the orbital period of A's spectroscopic binary difficult. B's spectroscopic companion was discovered in 1989, and that binary has a period of 33.01 years.

This star system has a peculiar velocity of 34.5 ± 5.9 km/s.

Edvard Grieg

Edvard Hagerup Grieg (Norwegian: [ ˈɛdʋɑɖ ˈhɑːɡərʉp ˈɡrɪɡ]; 15 June 1843 – 4 September 1907) was a Norwegian composer and pianist. He is widely considered one of the leading Romantic era composers, and his music is part of the standard classical repertoire worldwide. His use and development of Norwegian folk music in his own compositions put the music of Norway in the international spectrum, as well as helping to develop a national identity, much as Jean Sibelius and Antonín Dvořák did in Finland and Bohemia, respectively. Grieg is regarded as simultaneously nationalistic and cosmopolitan in his orientation, for although born in Bergen and buried there, he traveled widely throughout Europe, and considered his music to express both the beauty of Norwegian rural life and the culture of Europe as a whole. He is the most celebrated person from the city of Bergen, with numerous statues depicting his image, and many cultural entities named after him: the city's largest building (Grieg Hall), its most advanced music school (Grieg Academy), its professional choir (Edvard Grieg Kor), and even some private companies that include its largest hotel (Quality Hotel Edvard Grieg), and a music technology developer (Grieg Music). The Edvard Grieg Museum in Troldhaugen (Grieg's former home in Bergen) is dedicated to his legacy.

Bruno Mars

Peter Gene Hernandez (born October 8, 1985), professionally known by his stage name Bruno Mars, is an American singer, songwriter, record producer, and choreographer. Born and raised in Honolulu, Hawaii, by a family of musicians, Mars began making music at a young age and performed in various musical venues in his hometown throughout his childhood. He graduated from high school and moved to Los Angeles to pursue a musical career. Mars produced songs for other artists, co-founding the production team The Smeezingtons.

Mars had an unsuccessful stint with Motown Records, but then signed with Atlantic in 2009. He became recognized as a solo artist after lending his vocals to the songs "Nothin' on You" by B.o.B, and "Billionaire" by Travie McCoy, which were international successes, and for which he co-wrote the hooks. His debut studio album, Doo-Wops & Hooligans (2010), was anchored by the U.S. Billboard Hot 100 chart-topping singles "Just the Way You Are" and "Grenade", as well as the number-five single "The Lazy Song". His second album, Unorthodox Jukebox, released in 2012, peaked at number one in the United States. The album spawned the international singles "Locked Out of Heaven", "When I Was Your Man" and "Treasure".
