On chaotic behavior of gravitating stellar shells

M. V. Barkov, G. S. Bisnovatyi-Kogan, A. I. Neishtadt +1

Motion of two gravitating spherical stellar shells around a massive central body is considered. Each shell consists of point particles with the same specific angular momenta and en…

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…

Regular particle acceleration in relativistic jets

G. S. Bisnovatyi-Kogan

Exact solution is obtained for electromagnetic field around a conducting cylinder of infinite length and finite radius, with a periodical axial current, when the wave length is muc…
