Recent observations have revealed that the remnants of stellar-coalescence transients are
bipolar. This raises the questions of how these bipolar morphologies arise and what they …

The physical properties of X-ray novae as close binary systems are analysed. Observational
data in X-ray, UV, optical, IR and radio ranges are summarized. Modern theoretical …

Aims. Nonlinear behaviour of galactic dynamos is studied, allowing for magnetic helicity
removal by the galactic fountain flow. Methods. A suitable advection speed is estimated, and …

In some semidetached binary systems, the donor star may transfer mass to the companion at
a very high rate. We propose that, at sufficiently high mass-transfer rates such that the …

We present an analysis of multi-epoch spectroscopic and photometric observations of the
WZ Sge-type dwarf nova BW Scl, a period-bouncer candidate. We detected multiple …

Physics of Planetary Rings describes striking structures of the planetary rings of Saturn,
Uranus, Jupiter, and Neptune: Narrow ringlets, spiral waves, and a chain of clumps. The …

For the first time, all available pseudo-Schwarzschild potentials are exhaustively used to
investigate the possibility of shock formation in hydrodynamic, inviscid, black hole accretion …

We perform 2D and 3D numerical simulations of an accretion disc in a close binary system
using the simplified flux vector splitting (SFS) finite volume method. In our calculations, the …

We analyze heating and cooling processes in accretion disks in binaries. For realistic
parameters of the accretion disks in close binaries (̇ M ≃ 10^-12-10^ 7 M_ ⊙/yr and α⋍ …
