Garik Israelian (Armenian: Գարիկ Իսրայելյան, born 1963) is an Armenian-Spanish astrophysicist and co-founder of the Starmus Festival. In 1999, Israelian and colleagues presented the first observational evidence that supernova explosions were responsible for the formation of stellar-mass black holes.

Early life and education

Garik Israelyan Shatinyan was born in 1963 in Yerevan in then-Soviet Armenia. Preferring music over studying, he quit school at the age of 16, playing rock guitar in bars. Israelian credits sci-fi film Solaris for piquing his interest in science fiction and inspiring him to go to university. He studied astrophysics under Viktor Ambartsumian at Yerevan State University, graduating in 1987 and completing his Ph.D. in 1992. His PhD and first articles were dedicated to radiation transfer theory. Israelian worked as a post-doctoral researcher at the Universities of Utrecht, The Netherlands; Brussels, Belgium; and Sydney, Australia.[2][3][4]

Career

Israelian has worked at the Institute of Astrophysics, Canary Islands (IAC) since 1997.[2] In 1999, Israelian and colleagues found the first observational evidence, based on data from the W. M. Keck Observatory, that supernova explosions are responsible for the formation of black holes.[5] The black hole binary system studied by Israelian and colleagues was GRO J1655- 40. This discovery was cited by Stephen Hawking in his lecture at Starmus in 2014.

In 2001, he proposed the "Lithium-6 test" to determine if a star has engulfed a planet or other gaseous or solid matter.[6][non-primary source needed] He and collaborators proposed that a solar-type star HD82943 with two giant planets has swallowed a massive planet or a large amount of small rocky matter.[7]

He has been a visiting professor at Caltech (2002), University of Geneva (2001) and National Astronomical  Observatory of Japan and the University of Tokyo (2003).

In 2009, he and colleagues discovered that stars with planets, such as the sun, tend to have much less lithium.[8] He was invited to speak at TED Global in Oxford later that year.[9]

In June 2016, Israelian appeared on Larry King Now with Stephen Hawking to discuss Starmus Festival and extrasolar planets.[10]

Starsounds and Starmus

In 2005, Israelian compiled a library of acoustic sound waves produced within the bodies of stars.[11] In 2013, Brian May and the band Tangerine Dream used the starsounds in their composition Supernovae,[12] and in 2016 Brian Eno arranged some of Israelian's star recordings into a composition titled Starsounds.[11]

In 2011, together with astrophysicist and musician Brian May, Israelian and May created Starmus, a festival that would bring together the stars and music.[13] The concept of the Starsounds project was explained in Israelian's lecture "Our Acoustic Universe" at the first Starmus Festival and published in 2014 in the book Starmus: 50 Years of Man in Space.[14]

Awards

In 2010, Michel Mayor, Nobel laureate in Physics, Israelian, and Nuno Santos were awarded the Viktor Ambartsumian International Prize "[f]or their important contribution in the study of relation between planetary systems and their host stars."[1]

In 2014, Israelian received The Canary Islands Gold Medal, awarded by the government of the Canary Islands.[15]

On 20 June 2016, the International Astronomical Union and the Minor Planet Center officially renamed asteroid (21057) 1991 GJ8 to Garikisraelian in honor of Israelian.[16]
