Magnetorotational neutron star kicks
Ilya A. Kondratyev, Sergey G. Moiseenko, Gennady S. Bisnovatyi-Kogan
High velocity neutron stars, observed as rapidly moving radio-pulsars, are believed to gain high linear velocities -- kicks -- in aspherical supernova explosions. The mechanism of…
Optical and X-ray behaviour of the high mass X-ray transient A0535+26/HDE245770 in February-March 2014
F. Giovannelli, G. S. Bisnovatyi-Kogan, I. Bruni +3
The optical behaviour of the Be star in the high-mass X-ray transient A0535+26/HDE245770 shows that at periastron the luminosity is typically enhanced by 0.02 to a few tenths magni…
Galactic cluster winds in presence of a dark energy
G. S. Bisnovatyi-Kogan, M. Merafina
We obtain a solution for the hydrodynamic outflow of the polytropic gas from the gravitating center, in presence of the uniform Dark Energy (DE). The antigravity of DE is enlighten…
Dark energy and key physical parameters of clusters of galaxies
G. S. Bisnovatyi-Kogan, A. D. Chernin
We study physics of clusters of galaxies embedded in the cosmic dark energy background. Under the assumption that dark energy is described by the cosmological constant, we show tha…
Polytropic configurations with non-zero cosmological constant
M. Merafina, G. S. Bisnovatyi-Kogan, S. O. Tarasov
We solve the equation of the equilibrium of the gravitating body, with a polytropic equation of state of the matter , with , in the frame of the Newtonian gravity,…
Magnetorotational mechanism of supernova type II exlosion
S. G. Moiseenko, G. S. Bisnovatyi-Kogan, N. V. Ardeljan
Results of 2D simulations of the magnetorotational mechanism of supernova type II are presented. Amplification of toroidal magnetic field of the star due to differential rotation o…
