Fast giant flares in discs around supermassive black holes

G. V. Lipunova, A. S. Tavleev, K. L. Malanchev

We studied the thermal stability of non-self-gravitating turbulent -discs around supermassive black holes (SMBHs) to test a new type of high-amplitude galactic nucleus flares. B…

The effect of thermal winds on the outbursts evolution of LMXB systems

A. L. Avakyan, G. V. Lipunova, K. L. Malanchev

Theoretical models of accretion discs and observational data indicate that the X-ray emission from the inner parts of an accretion disc can irradiate its outer regions and induce a…

Physical modeling of viscous disc evolution around magnetized neutron star. Aql X-1 2013 outburst decay

Galina Lipunova, Konstantin Malanchev, Sergey Tsygankov +3

We present a model of a viscously evolving accretion disc around a magnetized neutron star. The model features the varying outer radius of the hot ionized part of the disc due to c…

Change in the orbital period of a binary system due to an outburst in a windy accretion disc

A. L. Avakyan, G. V. Lipunova, K. L. Malanchev +1

We consider a new mechanism for the removal of the angular momentum from an X-ray binary system and the change in its orbital period - the mass loss in the form of a wind from an a…

Multi-wavelenth monitoring of the changing-look AGN NGC 2617 during state changes

V. L. Oknyansky, C. M. Gaskell, N. A. Huseynov +18

Optical and near-infrared photometry, optical spectroscopy, and soft X-ray and UV monitoring of the changing-look active galactic nucleus NGC 2617 show that it continues to have th…

3D modelling of accretion disc in eclipsing binary system V1239 Her

V. V. Lukin, K. L. Malanchev, N. I. Shakura +3

We present the results of 3D-hydrodynamical simulations of accretion flow in the eclipsing dwarf nova V1239 Her in quiescence. The model includes the optical star filling its Roche…
