High-mass X-ray binaries are fundamental in the study of stellar evolution, nucleosynthesis,
structure and evolution of galaxies and accretion processes. Hard X-rays observations by …

Accreting X-ray pulsars are among the most luminous objects in the X-ray sky. In highly
magnetized neutron stars (B~ 10^ 12 G), the flow of matter is dominated by the strong …

Cyclotron lines, also called cyclotron resonant scattering features are spectral features,
generally appearing in absorption, in the X-ray spectra of objects containing highly …

The first X-ray pulsar, Cen X-3, was discovered 50 yr ago. Radiation from such objects is
expected to be highly polarized due to birefringence of plasma and vacuum associated with …

We investigate the relation between the optical extinction (AV) and the hydrogen column
density (NH) determined from X-ray observations of a large sample of Galactic sightlines …

Aims. We introduce a method for extracting spectral information from energy-resolved light
curves folded at the neutron star spin period (known as pulse profiles) in accreting X-ray …

We present the results of the neutron star X-ray binary system Cen X-3 performed by Insight-
HXMT with two observations during 2017 and 2018. During these two observations, the …

Because of its complex clumpy wind, prominent cyclotron resonant scattering features,
intrinsic variability, and convenient physical parameters (close distance, high inclination …

Bright and eclipsing, the high-mass X-ray binary Vela X-1 offers a unique opportunity to
study accretion onto a neutron star from clumpy winds of O/B stars and to disentangle the …

Context. Accreting highly magnetized pulsars in binary systems are among the brightest X-
ray emitters in our Galaxy. Although a number of high-quality broad-band (0.1–100 keV) X …
