The evolution of relative frequencies of ONe and CO SNe Ia
A. I. Bogomazov, A. V. Tutukov
In this population synthesis work we study a variety of possible origin channels of supernovae type Ia (SNe Ia) Among them mergers of carbon-oxygen (CO) and oxygen-neon (ONe) white…
Population synthesis of AX J1745.6-2901 X-ray nova type binaries with rapidly decreasing orbital periods
A. I. Bogomazov, A. M. Cherepashchuk, T. S. Khruzina +1
The neutron star low mass X-ray binary (LMXB) AX J1745.6-2901 was detected an anomalously fast decrease of orbital period. The decreasing rate of orbital period exceeds the contrib…
Optical, J, and K light curves of XTE J1118+480 = KV UMa: the mass of the black hole and the spectrum of the non-stellar component
A. M. Cherepashchuk, N. A. Katysheva, T. S. Khruzina +3
Optical, J, and K photometric observations of the KV UMa black hole X-ray nova in its quiescent state obtained in 2017-2018 are presented. A significant flickering within light cur…
CG X-1: an eclipsing Wolf-Rayet ULX in the Circinus galaxy
Yanli Qiu, Roberto Soria, Song Wang +7
We investigated the time-variability and spectral properties of the eclipsing X-ray source Circinus Galaxy X-1 (GG X-1), using Chandra, XMM-Newton and ROSAT. We phase-connected the…
Spin of LIGO/VIRGO merging black holes as the result of binary evolution
A. I. Bogomazov, V. M. Lipunov, A. V. Tutukov +1
Recently discovered bursts of gravitational waves provide a good opportunity to verify the current view on the evolution of close binary stars. Modern population synthesis computer…
Wolf-Rayet stars, black holes and the first detected gravitational wave source
A. I. Bogomazov, A. M. Cherepashchuk, V. M. Lipunov +1
The recently discovered burst of gravitational waves GW150914 provides a good new chance to verify the current view on the evolution of close binary stars. Modern population synthe…
A Study of the Evolution of the Close Binaries Cyg X-3, IC 10 X-1, NGC 300 X-1, SS 433, and M33 X-7 Using the "Scenario Machine"
A. I. Bogomazov
Evolutionary tracks for the X-ray binaries Cyg X-3, IC 10 X-1, NGC 300 X-1, SS 433, and M33 X-7 are computed using the Scenario Machine code. The compact objects in IC 10 X-1, NGC…
INTEGRAL observations of SS433: system's parameters and nutation of supercritical accretion disk
A. M. Cherepashchuk, R. A. Sunyaev, S. V. Molkov +3
Based on multiyear INTEGRAL observations of SS433 in 2003-2011, a composite IBIS/ISGRI 18-60 keV orbital light curve is constructed around zero precessional phases psi_{pr}= 0 at t…
Magnetars, Gamma-ray Bursts, and Very Close Binaries
A. I. Bogomazov, S. B. Popov
We consider the possible existence of a common channel of evolution of binary systems, which results in a gamma-ray burst during the formation of a black hole or the birth of a mag…
Population synthesis of gamma-ray bursts with precursor activity and the spinar paradigm
G. V. Lipunova, E. S. Gorbovskoy, A. I. Bogomazov +1
We study statistical properties of long gamma-ray bursts (GRBs) produced by the collapsing cores of WR stars in binary systems. Fast rotation of the cores enables a two-stage colla…
