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…
Parameters of X-ray binary system Scorpius X-1
A. M. Cherepashchuk, T. S. Khruzina, A. I. Bogomazov
We modelled optical light curves of Sco~X-1 obtained by the Kepler space telescope during K2 mission. Modelling was performed for the case of the strong heating of the optical star…
Gamma Ray Burst studies with THESEUS
G. Ghirlanda, R. Salvaterra, M. Toffano +30
Gamma-ray Bursts (GRBs) are the most powerful transients in the Universe, over-shining for a few seconds all other -ray sky sources. Their emission is produced within narrowly c…
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…
