A large energy-dependent X-ray polarization degree is detected by the Imaging X-ray Polarimetry Explorer (IXPE) in the high-soft emission state of the black hole X-ray binary 4U 1630–47. The highly significant detection (at ≈50 σ confidence leve

Mean opacities of a strongly magnetized high temperature plasma

Autor: Valery F Suleimanov, Alexander A Mushtukov, Igor Ognev, Victor A Doroshenko, Klaus Werner

Publikováno v: Monthly Notices of the Royal Astronomical Society, 517(3), 4022-4033

Geometry and dynamical structure of emission regions in accreting pulsars are shaped by the interplay between gravity, radiation, and strong magnetic field, which significantly affects the opacities of a plasma and radiative pressure under such extre

Importance of electron-positron pairs on the maximum possible luminosity of the accretion columns in ULXs

Autor: Valery F. Suleimanov, Alexander Mushtukov, Igor Ognev, Victor A. Doroshenko, Klaus Werner

One of the models explaining the high luminosity of pulsing ultra-luminous X-ray sources (pULXs) was suggested by Mushtukov et al. (2015). They showed that the accretion columns on the surfaces of highly magnetized neutron stars can be very luminous

Statistics of white dwarf properties in intermediate polars

Autor: Klaus Werner, Valery F. Suleimanov, Victor Doroshenko

Publikováno v: Proceedings of the International Astronomical Union. 15:202-205

Many intermediate polars are hard X-ray sources. The theory of their hard X-ray radiation is well developed and allows us to determine white dwarf masse in this kind of cataclysmic variables. Here we present the results of determination the masses of
