Excitation of turbulence in accretion disks of binary stars by non-linear perturbations
E. P. Kurbatov, D. V. Bisikalo
Accretion disks in binary systems can experience hydrodynamic impact at inner as well as outer edges. The first case is typical for protoplanetary disks around young T Tau stars. T…
A collimated wind interpretation for the spectral variability of Z And during its major 2006 eruption
N. A. Tomov, M. T. Tomova, D. V. Bisikalo
High-resolution observations in the region, centered at 4400 Å and those of the lines HeII 4686, Hbeta and HeI 6678 of the spectrum of the symbiotic binary Z And were performed dur…
A Numerical Model for Accretion in Intermediate Polars with Dipolar Magnetic Fields
P. B. Isakova, A. G. Zhilkin, D. V. Bisikalo
A three-dimensional numerical model for an accretion process investigation in the magnetosphere of a white dwarf in magnetic cataclysmic variables is developed. The model assumes t…
Transient accretion disc-like envelope in the symbiotic binary BF Cygni during its 2006 - 2015 optical outburst
N. A. Tomov, M. T. Tomova, D. V. Bisikalo
The optical light of the symbiotic binary BF Cygni during its last eruption after 2006 shows orbital variations because of an eclipse of the outbursting compact object. The first o…
Symbiotic Stars with Similar Line Profiles during Activity
N. A. Tomov, M. T. Tomova, D. V. Bisikalo
Line profiles containing indication of bipolar collimated outflow along with P Cyg absorption during phase of activity of several symbiotic systems are considered. The Hgamma profi…
