This work considers a theoretical model for quasi-spherical subsonic accretion onto slowly rotating magnetized neutron stars. In this regime the accreting matter settles down subsonically onto the rotating magnetosphere, forming an extended quasi-static shell. The shell mediates the angular momentum transfer to/from the rotating neutron star magnetosphere by large-scale convective motions, which for observed pulsars lead to an almost so-angular-momentum rotation law with ω ∼ 1/R inside the…

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 settles with subsonic velocities onto the rotating
Wind accretion: Theory and observations
A review of wind accretion in high-mass X-ray binaries is presented. We focus on different regimes of quasi-spherical accretion onto the neutron star (NS): the supersonic (Bondi) accretion, which
Bright flares in supergiant fast X-ray transients
At steady low-luminosity states, Supergiant Fast X-ray Transients (SFXTs) can be at the stage of quasi-spherical settling accretion onto slowly rotatin g magnetized neutron stars from the
Settling accretion on to isolated neutron stars from interstellar medium
We apply the model of subsonic settling accretion on to isolated neutron stars accreting from the interstellar medium (AINS). We show that in this regime the expected mean X-ray luminosity from AINS
Formation of wind-captured discs in Supergiant X-ray binaries : consequences for Vela X-1 and Cygnus X-1.
In Supergiant X-ray binaries (SgXB), a compact object captures a fraction of the wind of an O/B supergiant on a close orbit. Proxies exist to evaluate the efficiency of mass and angular momentum
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 star. Neutron stars in X-ray binaries have magnetic
Symbiotic X-ray binaries systems in the galaxy
The evolution of symbiotic X-ray binaries in the Galaxy is studied by the population synthesis method. We show that allowance for the nonstationarity of the regime of quasi-spherical subsonic
Bondi–Hoyle–Lyttleton accretion in supergiant X-ray binaries: stability and disc formation
We use 2D (axisymmetric) and 3D hydrodynamic simulations to study Bondi–Hoyle–Lyttleton accretion with and without transverse upstream gradients. We mainly focus on the regime of high (upstream)
Radiography in high mass X-ray binaries
Context.In high mass X-ray binaries, an accreting compact object orbits a high mass star, which loses mass through a dense and inhomogeneous wind.Aims.Using the compact object as an X-ray backlight,
Spin-up/spin-down of neutron star in Be-X-ray binary system GX 304-1
ABSTRACT We analyze spin-up/spin-down of the neutron star in Be X-ray binary system GX304-1 ob-served by Swift/XRT and Fermi/GBM instruments in the period of the source activity fromApril 2010 to
