    Evolution of the accretion structure of the compact object in the symbiotic binary BF Cygni during outburst in 2009–2014

    The eclipsing symbiotic binary BF Cyg has had five orbital minima during its last optical outburst after 2006. The second minimum is much shallower than the first one and after that the minimum get deeper agai...

    Gaseous flows in the inner part of the circumbinary disk of the T Tauri star

    We present results of 3D numerical simulations of the matter flow in the disk of a binary T Tauri star. It is shown that two bow-shocks caused by the supersonic motion of the binary components in the gas of th...

    On Possible Nature of Pre-eclipse Dips in Light Curves of Semi-detached Systems with Steady-state Disks

    In order to explain pre-eclipse dips at phases ~0.7 in light curves of cataclysmic variables, the hypothesis of the thickening at the outer edge of the accretion disk is usually used. Shock-free nature of the ...
