Quasi-spherical accretion in X-ray pulsars
K. Postnov, N. Shakura, A. Kochetkova +1
Quasi-spherical accretion in wind-fed X-ray pulsars is discussed. At X-ray luminosities <4 10^{36} erg/s, a hot convective shell is formed around the neutron star magnetosphere, an…
Spin period evolution of GX 1+4
A. González-Galán, E. Kuulkers, P. Kretschmar +4
We aim both to complement the existing data on the spin history of the peculiar accreting X-ray pulsar GX 1+4 with more past and current data from BeppoSAX, INTEGRAL, and Fermi and…
Theory of quasi-spherical accretion in X-ray pulsars
N. Shakura, K. Postnov, A. Kochetkova +1
A theoretical model for quasi-spherical subsonic accretion onto slowly rotating magnetized neutron stars is constructed. In this model the accreting matter subsonically settles dow…
Wind accretion in symbiotic X-ray binaries
K. Postnov, N. Shakura, A. González-Galán +7
The properties of wind accretion in symbiotic X-ray binaries (SyXBs) consisting of red-giant and magnetized neutron star (NS) are discussed. The spin-up/spin-down torques applied t…
Pulse period evolution of GX 1+4
A. González-Galán, E. Kuulkers, P. Kretschmar +4
We report on the long-term evolution of the spin period of the symbiotic X-ray pulsar GX 1+4 and a possible interpretation within a model of quasi-spherical accretion. New period m…
