We consider the physical characteristics and dynamics of the gaseous envelopes of hot
Jupiters (HJs)—gas giants with a mass comparable to Jupiter's and a semi-major axis of less …

The current understanding of mass exchange processes between close binary system
(CBS) components is reviewed, with particular attention on the mass flow structure and …

The article presents a review of scientific problems and methods of ultraviolet astronomy,
focusing on perspective scientific problems (directions) whose solution requires UV space …

We present the results of a 3D global magnetohydrodynamic (MHD) simulation of an AM
CVn system that was aimed at exploring eccentricity growth in the accretion disc self …

We have performed three-dimensional magnetohydrodynamical calculations of stream
accretion in cataclysmic variable stars for which the white dwarf primary possesses a strong …

We consider the structure and formation of the circumbinary envelopes in semi-detached
binary systems. Three-dimensional numerical simulations of the gas dynamics are used to …

Accretion disks around black hole, neutron star, and white dwarf systems are thought to
sometimes tilt, retrogradely precess, and produce hump-shaped modulations in light curves …

Planet formation scenarios and the observed planetary dynamics in binaries pose a number
of theoretical challenges, especially concerning circumbinary planetary systems. We explore …

Net tidal torque by the secondary on a misaligned accretion disk, like the net tidal torque by
the Moon and the Sun on the equatorial bulge of the spinning and tilted Earth, is suggested …

The current status of the physics of accretion disks in close binary stars is reviewed, with an
emphasis on the hydrodynamic overreflection instability, which is a factor leading to the …
