In the present work we have computed the ON- and OFF-state generations on high resolution grid for microquasar CYG X-1. The results shows that in disk the ON-state time intervals are equal to OFF- state time intervals and these intervals are equal to

In the present work we have com- puted the thick accretion disk (the accretion disk with radiation pressure) for the case of undefined precession over very long time (more than 14 precession periods). The calculations show that in this case the origi

The thick accretion disk and donor’s wind on the example of CYG X-1 are computed. The main aim of the present simulations is to calculate the precessing thick accretion disk and ON- and OFF-state generation by the methods of 3D numerical hydrodynam

2D and 3D mass transfer simulations of the mass transfer in β Lyrae binary system. We have received that from a point L3 40 percent of mass transfer from L1-point is lost. The structure of a gas envelope, around system is calculated. 3-D mass transf

In the present research we have calculated 3D numerical hydrodynamical simulations of a radiation-driven jet launch and disappearing over low/hard state. The calculations show that the jet launch occurs at the beginning of the low/hard state over 10-

In this study, the models of slaved precession of accretion disc and donors radiationdriven wind were performed using three-dimensional numerical astrophysical methods by the example of microquasar Cyg X-1. As is shown, in the course of precession of

Analysis of the properties of the eclipsing binary stars shows, that the stream-like mechanism of the mass transfer switches on at a contact evolutionary stage, preceding to a stage of binaries with a subgiant. The computations of the gas streams nea

As is shown in the present computations performed using three-dimensional numerical astrophysical methods, in microquasars in the course of precession of the accretion disc blown by the donor’s wind the on- and off-states start being generated in t
