Professor Alexey Starobinsky, an outstanding physicist and world-class scientist, a specialist in the gravity and cosmology of the early universe, academician of the Russian Academy of Sciences, professor at HSE University, and Fellow of the CORE Academy, has died at the age of 75.

Alexei A. Starobinsky is a theoretical physicist recognized for his work in gravity, cosmology, and astrophysics. He is known particularly as one of the authors of the theory of a quasi-de Sitter (inflationary) stage preceding the hot Big Bang (radiation-dominated stage) in the early Universe (for his papers beginning from 1979), as well for his works on super-radiance and creation of particles by rotating black holes (1973).

He was born in Moscow, USSR, in 1948 and grew up there, He graduated from the Moscow State University in 1972 with a MSc degree in physics and then was a postgraduate student at the Landau Institute for Theoretical Physics of the USSR (now Russian) Academy of Sciences, Moscow - Chernogolovka, where he got his PhD in theoretical and mathematical physics in 1975. Since that time he was a staff member at this institute keeping positions of a researcher, senior researcher, Science secretary, leading researcher, Head of the Department, Vice-Director and principal researcher in possession. He also spent much time as a visiting professor at the University of Tokyo and the Yukawa Institute for Theoretical Physics, Kyoto, Japan, Ecole Normale Superieure, Paris, France; Institute of Theoretical Physics, Utrecht University, Netherlands; Inter-University Center for Astronomy and Astrophysics, Pune, India and other universities in different countries. 

He is a member of the Russian Academy of Sciences (Correspondent Member – 1997, Full Member – 2011), the Academy Leopoldina—the German National Academy of Sciences (2010), the Norwegian Academy of Science and Letters (2014), a Foreign Fellow of the Indian National Academy of Sciences, India (2013), the US National Academy of Sciences (2017), and a Fellow of the American Physical Society (2011). He is also a recipient of the Kavli, Gruber, Friedmann and Tomalla prizes and Gold Sakharov, Oscar Klein, Amaldi and Friedmann medals for his research.

The CORE Academy mourns together with Prof. Starobinsky's friends, students, and relatives.
