Real-time observations of the transition to the quiescent state in an accreting magnetised neutron star: No propeller required?
Sergey S. Tsygankov, Galina Lipunova, Valery F. Suleimanov +6
The final stages of outbursts in transient X-ray pulsars (XRPs), which are characterised by a significant decline in the mass accretion rate, provide valuable insight into the phys…

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.…

Application of hydrostatic local thermodynamic equilibrium atmosphere models to interpretations of supersoft X-ray source spectra
V. F. Suleimanov, A. S. Tavleev, V. Doroshenko +1
Supersoft X-ray sources (SSSs) are accreting white dwarfs (WDs) with stable or recurrent thermonuclear burning on their surfaces. High-resolution X-ray spectra of such objects are…
