Bright X-ray pulsars as sources of MeV neutrinos in the sky
Aman Asthana, Alexander A. Mushtukov, Alexandra A. Dobrynina +1
High mass accretion rate onto strongly magnetised neutron stars results in the appearance of accretion columns supported by the radiation pressure and confined by the strong magnet…
IXPE observations of the quintessential wind-accreting X-ray pulsar Vela X-1
Sofia V. Forsblom, Juri Poutanen, Sergey S. Tsygankov +97
The radiation from accreting X-ray pulsars was expected to be highly polarized, with some estimates for the polarization degree of up to 80%. However, phase-resolved and energy-res…
Statistical features of multiple Compton scattering in a strong magnetic field
Alexander A. Mushtukov, Ivan D. Markozov, Valery F. Suleimanov +4
Compton scattering is a key process shaping spectra formation and accretion flow dynamics in accreting strongly magnetized neutron stars. A strong magnetic field affects the scatte…
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…
Luminosity dependence of the cyclotron line and evidence for the accretion regime transition in V 0332+53
Victor Doroshenko, Sergey S. Tsygankov, Alexander A. Mushtukov +4
We report on the analysis of NuSTAR observations of the Be-transient X-ray pulsar V 0332+53 during the giant outburst in 2015 and another minor outburst in 2016. We confirm the cyc…
Transient X-ray pulsar V0332+53: pulse phase-resolved spectroscopy and the reflection model
A. A. Lutovinov, S. S. Tsygankov, V. F. Suleimanov +4
We present the results of the pulse phase- and luminosity-resolved spectroscopy of the transient X-ray pulsar V0332+53, performed for the first time in a wide luminosity range (1-4…
