Variable neutron star free precession in Hercules X-1 from evolution of RXTE X-ray pulse profiles with phase of the 35-day cycle
K. Postnov, N. Shakura, . R. Staubert +3
Accretion of matter onto the surface of a freely precessing NS with a complex non-dipole magnetic field can explain the change of X-ray pulse profiles of Her X-1 observed by RXTE w…
Do we see accreting magnetars in X-ray pulsars?
K. A. Postnov, N. I. Shakura, A. Yu. Kochetkova +1
Strong magnetic field of accreting neutron stars ( G) is hard to probe by X-ray spectroscopy but can be indirectly inferred from spin-up/spin-down measurement in X-ray pul…
Theory of wind accretion
N. I. Shakura, K. A. Postnov, A. Yu. Kochetkova +1
A review of wind accretion in high-mass X-ray binaries is presented. We focus attention to different regimes of quasi-spherical accretion onto the neutron star: the supersonic (Bon…
Settling accretion onto slowly rotating X-ray pulsars
N. I. Shakura, K. A. Postnov, A. Yu. Kochetkova +1
Quasi-spherical subsonic accretion onto slowly rotating magnetized NS is considered, when the accreting matter settles down subsonically onto the rotating magnetosphere, forming an…
