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…
Three-dimensional modelling of accretion columns: spatial asymmetry and self-consistent simulations
M. I. Gornostaev
The paper presents the results of three-dimensional (3D) modelling of the structure and the emission of accretion columns formed above the surface of accreting strongly magnetized…
Comptonization of CMB in galaxy clusters. Monte Carlo computations
M. I. Gornostaev, G. V. Lipunova
The problem under consideration is to determine the change of the Cosmic Microwave Background (CMB) spectral shape due to the thermal Sunyaev-Zeldovich effect. We numerically model…
Luminosity-dependent changes of the cyclotron line energy and spectral hardness in Cep X-4
V. Vybornov, D. Klochkov, M. Gornostaev +5
X-ray spectra of accreting pulsars are generally observed to vary with their X-ray luminosity. In particular, the hardness of the X-ray continuum is found to depend on luminosity.…
On the dependence of the X-ray continuum variations with luminosity in accreting X-ray pulsars
K. A. Postnov, M. I. Gornostaev, D. Klochkov +3
Using RXTE/ASM archival data, we investigate the behaviour of the spectral hardness ratio as a function of X-ray luminosity in a sample of six transient X-ray pulsars (EXO 2030+375…
