Screening of the Magnetic Field of Disk Accreting Stars
R. V. E. Lovelace, M. M. Romanova, G. S. Bisnovatyi-Kogan
An analytical model is developed for the screening of the external magnetic field of a rotating, axisymmetric neutron star due to the accretion of plasma from a disk. The decrease…
A Simplified Model of the Formation of Structures in Dark Matter
O. Yu. Tsupko, G. S. Bisnovatyi-Kogan
The collapse of a rotating 3-axis ellipsoid is approximated by a system of ordinary differential equations. Violent relaxation, mass and angular momentum losses are taken into acco…
Magnetorotational supernova simulations
S. G. Moiseenko, G. S. Bisnovatyi-Kogan, N. V. Ardeljan
We present 2D results of simulations of the magnetorotational core collapsed supernova. For the first time we obtain strong explosion for the core collapsed supernova. In 2D approx…
Gamma-ray burst interaction with dense interstellar medium
Maxim Barkov, Gennady Bisnovatyi-Kogan
Interaction of cosmological gamma ray burst radiation with the dense interstellar medium of host galaxy is considered. Gas dynamical motion of interstellar medium driven by gamma r…
Collimated high-energy photons and others possible observational effects of the photon angular and spectral distribution in gamma-ray bursts sources
V. V. Sokolov, V. G. Kurt, G. S. Bisnovatyi-Kogan +4
Typical observational gamma-ray burst (GRB) spectra are discussed and, in this connection, what is the origin of the compactness problem and how it was solved at first. If the thre…
Accretion disks around black holes with account of magnetic fields
G. S. Bisnovatyi-Kogan
Accretion disks are observed in young stars, cataclysmic variables, binary X-ray sources et al. Accretion disk theory was first developed as a theory with the local heat balance, w…
