On the radiation beaming of bright X-ray pulsars and constraints on neutron star mass-radius relation

Alexander A. Mushtukov, Patrick A. Verhagen, Sergey S. Tsygankov +3

The luminosity of accreting magnetised neutron stars can largely exceed the Eddington value due to appearance of accretion columns. The height of the columns can be comparable to t…

Propagating mass accretion rate fluctuations in X-ray binaries under the influence of viscous diffusion

Alexander A. Mushtukov, Adam Ingram, Michiel van der Klis

Many statistical properties of X-ray aperiodic variability from accreting compact objects can be explained by the propagating fluctuations model applied to the accretion disc. The…

Stable accretion from a cold disc in highly magnetized neutron stars

S. S. Tsygankov, A. A. Mushtukov, V. F. Suleimanov +4

The aim of this paper is to investigate the transition of a strongly magnetized neutron star into the accretion regime with very low accretion rate. For this purpose we monitored t…

SMC X-3: the closest ultraluminous X-ray source powered by a neutron star with non-dipole magnetic field

S. S. Tsygankov, V. Doroshenko, A. A. Lutovinov +2

Magnetic field of accreting neutron stars determines their overall behaviour including the maximum possible luminosity. Some models require an above-average magnetic field strength…

Optically thick envelopes around ULXs powered by accreating neutron stars

Alexander A. Mushtukov, Valery F. Suleimanov, Sergey S. Tsygankov +1

Magnetized neutron stars power at least some ultra-luminous X-ray sources. The accretion flow in these cases is interrupted at the magnetospheric radius and then reaches the surfac…
