Young neutron stars with soft gamma ray emission and anomalous X-ray pulsar
G. S. Bisnovatyi-Kogan
The observational properties of Soft Gamma Repeaters and Ano\-malous X-ray Pulsars (SGR/AXP) indicate to necessity of the energy source different from a rotational energy of a neut…
Evolutions of Neutron Stars and their Magnetic Fields
G. S. Bisnovatyi-Kogan
Estimations of magnetic fields of neutron stars, observed as radio and X-ray pulsars, are discussed. It is shown, that theoretical and observational values for different types of r…
Estimation of alpha-viscosity coefficient from observations of nonstationary disk accretion
G. S. Bisnovatyi-Kogan, A. S. Klepnef, F. Giovannelli
The optical behaviour of the Be star in the high mass X-ray transient A0535+26/HDE245770 shows that at the periastron typically there is an enhancement in the luminosity of order 0…
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…
Accretion into black holes with magnetic fields, and relativistic jets
G. S. Bisnovatyi-Kogan, A. S. Klepnev, R. V. E. Lovelace
We discuss the problem of the formation of a large-scale magnetic field in the accretion disks around black holes, taking into account the non-uniform vertical structure of the dis…
Models of high-luminosity accretion disks surrounding black holes
A. S. Klepnev, G. S. Bisnovatyi-Kogan
The problem of steady-state accretion to nonrotating black holes is examined. Advection is included and generalized formulas for the radiation pressure in both the optically thick…
