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 …

Using a consistent set of models, we parameterized the X-ray spectra of all accreting pulsars
in the Rossi X-Ray Timing Explorer (RXTE) database that exhibit cyclotron resonance …

We develop a new theoretical model for the spectral formation process in accretion-powered
X-ray pulsars based on a detailed treatment of the bulk and thermal Comptonization …

The launch of the IXPE telescope in late 2021 finally made polarization measurements in the
2–8 keV band a reality, more than 40 years after the pioneering observations of the OSO-8 …

Cyclotron resonance scattering features observed in the spectra of some X-ray pulsars show
significant changes of the line energy with the pulsar luminosity. At high luminosities, these …

We present a catalogue of high-mass X-ray binaries. The catalogue is an updated version of
the catalogue of van Paradijs (1995). This new catalogue contains 130 sources, 61 new …

The spectra of many X-ray pulsars show, in addition to a power law, a low-energy
component that has often been modeled as a blackbody with kT BB~ 0.1 keV. However, the …

Some of the accreting X-ray pulsars are reported to exhibit a peculiar spectral feature at∼
10 keV, known as the '10 keV feature'. The feature has been characterized as either an …

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 …
