THREE-DIMENSIONAL NUMERICAL HYDRODYNAMIC SIMULATION OF ON- AND OFF-STATES IN MICROQUASARS AND QUASARS

Анотація

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
the disc. In our case, the transition between these
states takes 30-40 minutes of the orbital time. In
the off-state the temperature changes discretely, i.e.
such a change appears as separate sharp peaks, which
almost merge with each other over time.
