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…
The curtain remains open: NGC 2617 continues in a high state
V. L. Oknyansky, C. M. Gaskell, N. A. Huseynov +17
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…
Determination of the turbulent parameter in the accretion disks: effects of self-irradiation in 4U 1543-47 during the 2002 outburst
G. V. Lipunova, K. L. Malanchev
We investigate the viscous evolution of the accretion disk in 4U 1543-47, a black hole binary system, during the first 30 days after the peak of the 2002 burst by comparing the obs…
