Traces of wobbling accretion disk in X-ray pulsar Her X-1 from observations of the ART-XC telescope of the SRG observatory
V. M. Revnivtsev, K. A. Postnov, S. V. Molkov +5
Long uninterrupted observations of the X-ray binary system Her X-1 were performed with the Mikhail Pavlinsky ART-XC telescope of the Spectrum-Röntgen-Gamma (SRG) X-ray Observatory…
Evidence for neutron star triaxial free precession in Her X-1 from Fermi/GBM pulse period measurements
Dmitry Kolesnikov, Nikolai Shakura, Konstantin Postnov
Her X-1/HZ Her is one of the best studied accreting X-ray pulsars. In addition to the pulsating and orbital periods, the X-ray and optical light curves of the source exhibit an alm…
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…
eROSITA calibration and performance verification phase: High-mass X-ray binaries in the Magellanic Clouds
F. Haberl, C. Maitra, S. Carpano +8
During its performance verification phase, the soft X-ray instrument eROSITA aboard the Spektrum-Roentgen-Gamma(SRG) spacecraft observed large regions in the Magellanic Clouds, whe…
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…
X-ray emission from magnetized neutron star atmospheres at low mass accretion rates. I. Phase-averaged spectrum
E. Sokolova-Lapa, M. Gornostaev, J. Wilms +12
Recent observations of X-ray pulsars at low luminosities allow, for the first time, to compare theoretical models for the emission from highly magnetized neutron star atmospheres a…
