Quasi-spherical accretion in low-luminosity X-ray pulsars: Theory vs. observations
K. Postnov, N. Shakura, A. Kochetkova +1
Quasi-spherical subsonic accretion can be realized in slowly rotating wind-fed X-ray pulsars (XPSRs) at X-ray luminosities <4 10^{36} erg/s. In this regime the accreting matter set…

Spin period evolution of the X-ray pulsar 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…
