High-Mass X-ray Binaries
Binary systems in which a neutron star or black hole accretes material from a high-mass star are known as high-mass X-ray binaries (HMXBs). This...

Accreting Strongly Magnetized Neutron Stars: X-ray Pulsars
X-ray pulsars (XRPs) are accreting strongly magnetized neutron stars (NSs) in binary systems with, as a rule, massive optical companions. Very reach...

Quasi-Spherical Subsonic Accretion onto Magnetized Neutron Stars
A theory of quasi-spherical subsonic accretion onto slowly rotating magnetized neutron stars is presented. In this regime, the accreted matter...

X-Ray Pulsars
X-ray pulsars shine thanks to the conversion of the gravitational energy of accreted material to X-ray radiation. The accretion rate is modulated by...

Magnetic Fields of Neutron Stars in X-Ray Binaries
A substantial fraction of the known neutron stars resides in X-ray binaries—systems in which one compact object accretes matter from a companion...
