The massive binary system WR 20a: light curve analysis in a colliding wind model

I. I. Antokhin, E. A. Antokhina, A. M. Cherepashchuk

The article presents the results of the analysis of optical light curves of the massive binary system WR 20a (WN 6ha + WN 6ha). The analysis was performed with the binary system mo…

Near-IR and X-ray Variability of Cyg X-3: Evidence for a Compact IR Source and Complex Wind Structures

Igor I. Antokhin, Anatol M. Cherepashchuk, Eleonora A. Antokhina +1

We study near-infrared (JHK) and X-ray light curves of Cyg X-3 obtained with the 2.5-m telescope of the Caucasian Mountain Observatory of MSU SAI and collected from RXTE ASM and MA…

On the nature of the single eclipse per 80d orbit of the H-rich luminous WN star WR22

Guillaume Lenoir-Craig, Igor I. Antokhin, Eleonora A. Antokhina +2

WR22 = HD 92740 is a bright (V = 6.4 ), intrinsically luminous, double-line WN7h + O9III-V binary exhibiting one sharp 8\% deep eclipse near periastron in its elliptical (e =…

Discovery of a pre-cataclysmic binary with unusual chromaticity of the eclipsed white dwarf by the GPX Survey

Vadim Krushinsky, Paul Benni, Artem Burdanov +14

We report the discovery of a relatively bright eclipsing binary system, which consists of a white dwarf and a main sequence K7 star with clear signs of chromospheric and spot activ…

SS433: a massive X-ray binary at advanced evolutionary stage

Anatol Cherepashchuk, Konstantin Postnov, Sergey Molkov +2

INTEGRAL IBIS/ISGRI 18-60 keV observations of SS433 performed in 2003-2011 enabled the hard X-ray phase-resolved orbital and precessional light curves and spectra to be constructed…

Masses of optical components and black holes in x-ray novae: the effects of components proximity

V. S. Petrov, E. A. Antokhina, A. M. Cherepashchuk

An exact calculation of CaI A absorption profiles in the spectra of optical stars in low-mass X-ray binary systems with black holes (BH LMXBs) is carried out. We show th…
