A scenario of the formation of isolated X-ray pulsars with anomalously long period
N. R. Ikhsanov, V. Yu. Kim, N. G. Beskrovnaya
A scenario of the formation of isolated X-ray pulsars is discussed with an application to one of the best studied objects of this class 1E 161348-5055. This moderately luminous, 10…
Period clustering of the anomalous X-ray pulsars
G. S. Bisnovatyi-Kogan, N. R. Ikhsanov
In this paper we address the question of why the observed periods of the Anomalous X-ray Pulsars (AXPs) and Soft Gamma-ray Repeaters (SGRs) are clustered in the range 2-12 s. We ex…
On the origin of the peculiar cataclysmic variable AE Aquarii
N. G. Beskrovnaya, N. R. Ikhsanov
The nova-like variable AE Aquarii is a close binary system containing a red dwarf and a magnetized white dwarf rotating with the period of 33 seconds. A short spin period of the wh…
Spin evolution of long-period X-ray pulsars
N. R. Ikhsanov, Yu. S. Likh, N. G. Beskrovnaya
Spin evolution of X-ray pulsars in High Mass X-ray Binaries (HMXBs) is discussed under various assumptions about the geometry and physical parameters of the accretion flow. The tor…
Formation and appearance of pulsar-like white dwarfs
Nazar Ikhsanov, Nina Beskrovnaya
Accretion-driven spin-up of a magnetized white dwarf in a close binary system is discussed. We address a situation in which the magnetic field of the white dwarf is screening durin…
Evidence for Magneto-Levitation Accretion in Long-Period X-ray Pulsars
Nazar Ikhsanov, Nina Beskrovnaya, Yury Likh
Study of observed spin evolution of long-period X-ray pulsars challenges quasi-spherical and Keplerian disk accretion scenarios. It suggests that the magnetospheric radius of the n…
