# Dmitry V. Bisikalo

Dmitry Valerevich Bisikalo (born 1961) is a Russian astrophysicist and an expert in the interaction of binary stars. He is a member of the Russian Academy of Sciences, the IAU, Acting Chief of the Scientific Secretary of the Russian Academy of Sciences and Chief Researcher of the Institute of Astronomy of the Russian Academy of Sciences (RAS).

## Biography

Dmitry Bisikalo was born in 1961 in Irkutsk (Soviet Union). In 1984 he graduated from the Moscow Institute of Physics and Technology and started his PhD program at the Astronomical Council of the Academy of Sciences of the Soviet Union (now Institute of Astronomy of the Russian Academy of Sciences). In 1988 he defended his PhD thesis (title: Investigation of the Inner Comet Coma in the Frame of Continual and Molecular Gas Dynamics). In 1998 he obtained his Full Doctor degree (Doctor of Sciences) at the Sternberg Astronomical Institute of MSU (title: Investigation of Gas Dynamics of Mass Transfer in Interacting Binary Systems). Since 2001 Bisikalo has been the deputy director of the Institute of Astronomy of RAS (INASAN). In 2010 he was awarded the Professor of Astrophysics and in 2011 he was elected the Correspondent Member of the RAS. Since 2016 Bisikalo has been the Director of the Institute of Astronomy of the Russian Academy of Sciences. Since December 30, 2021 Bisikalo is Acting Chief of the Scientific Secretary of the Russian Academy of Sciences.

## Scientific career

Bisikalo is a specialist in the gas dynamics of interacting binary stars and accretion disks. He participates in the development of numerical methods of investigating astrophysical objects by the methods of molecular (solving the kinetic Boltzmann equation) and continual (Euler gas dynamic equations) gas dynamics. He has over 270 published papers, 5 monographs and 4 monographic reviews.

### Main achievements

* Development of the astrophysical direction that combines astrophysical observations with gas dynamical and MHD numerical simulations
* Creation of the self-consistent model of the mass transfer in binary stars
* Investigation of the accretion disk structure in binary stars
* Discovery of precessional density waves in cool accretion disks
* First investigations of the formation of common envelopes in close binary stars
* Description of the outburst activity of classical symbiotic stars based on the results of 3D gas dynamic simulations
* First investigations of the influence of magnetic field on the accretion disk structure in the intermediate polars
* Development of the numerical kinetic model of the interaction of upper planet atmospheres with high-energy particles originating in magnetospheres. The model is widely used in a number of space experiments (IMAGE, HST, MEX, VEX) to investigate the atmospheres of Earth, Venus, Mars, and Jupiter.
The works of D.V. Bisikalo are cited in the annual reports of the RAS.
