Bright X-ray Pulsars: how outflows influence beaming, pulsations and pulse phase lags

Alexander A. Mushtukov, Simon Portegies Zwart

Extreme accretion in X-ray pulsars (XRPs) results in radiation-driven outflows launched from the inner parts of the accretion disc. The outflows affect the apparent luminosity of t…

Mean opacities of a strongly magnetized high temperature plasma

Valery F. Suleimanov, Alexander A. Mushtukov, Igor Ognev +2

Geometry and dynamical structure of emission regions in accreting pulsars are shaped by the interplay between gravity, radiation, and strong magnetic field, which significantly aff…

Relation of cyclotron resonant energy and luminosity in a strongly magnetized neutron star GRO J1008-57 observed by Insight-HXMT

X. Chen, W. Wang, Y. M. Tang +10

Cyclotron line scattering features are detected in a few tens of X-ray pulsars (XRPs) and used as direct indicators of a strong magnetic field at the surface of accreting neutron s…

SRG/ART-XC and NuSTAR observations of the X-ray pulsar GRO J1008-57 in the lowest luminosity state

A. Lutovinov, S. Tsygankov, S. Molkov +6

We report results of the first broadband observation of the transient X-ray pulsar GRO J1008-57 performed in the quiescent state. Observations were conducted quasi-simultaneously w…

X-ray pulsar XTE J1858+034: discovery of the cyclotron line and the revised optical identification

Sergey S. Tsygankov, Alexander A. Lutovinov, Sergey V. Molkov +7

We present results of a detailed investigation of the poorly studied X-ray pulsar XTE J1858+034 based on the data obtained with the NuSTAR observatory during the outburst of the so…
