Biography:
He was born on March 21, 1943 in the of Nyandoma city Arkhalgen region of Russian SSR.
In 1966 he graduated from M. V. Lomonosov Moscow State University, where he entered in 1961.
During 1966-1969 he studied at the graduate school of the Crimean Astrophysical Observatory under the leadership of A. B. Severny.
In 1974 he defended his dissertation "Magnetic field and electric currents of sunspots".
Together with Lutiy V. M. performed a new analysis of the nucleus of the Seyfert galaxy NGC4151, which was studied in 1968-1986 using the U filter.
One of the results obtained by scientists in collaboration with Severny A. B. in the study of the velocity of radiation lines in the central region of the Sun is the detection of a period of velocity change of 160 minutes.
Together, T.T Tsap and Academician A. B. Severny developed a new direction in astronomy - helioseismology (according to other sources, he actively worked on this topic in the 1980s with A. G Kosovychev, A. B. Severny, T. T. Tsap, V. Dzhembovsky and D. Gaf). The discovery of global pulsations of the Sun by this group of authors was registered as a discovery in 1974. The period of pulsations then was Po = 9600.606 (12) p. Together with V. I. Khaneychuk it was discovered that after 1982 the period Pi = 9597.929 (15) p.
In 1994 he defended his doctoral dissertation "Study of the general magnetic field and periodic processes in the Sun" 15.05.2008 re-certification at the Main Astronomical Observatory of the NAS of Ukraine. In 2009 she was recognized in the Academy of Sciences of the Russian Federation.
He works as a leading researcher at the Crimean Astrophysical Observatory in the Laboratory of Solar Physics. During 1986-1992 he was deputy director.
He is a member of the International Astronomical Society.
His field of research is the physics of the Sun and solar-terrestrial relations, the study of nebulae and galaxies. Since 1965 he has been studying the Sun on the North Solar Tower Telescope, author of more than 300 scientific papers.
He was awarded the medals of the Exhibitions of achievements of the national economy, the Order of the Badge of Honor in 1981.
The asteroid #8246 which was discovered by N. S. Chernykh in 1979 received the name "Kotov" in honor of the astronomer.
