Peculiarities in the orbital and precessional variability of SS433 from INTEGRAL observations
A. Cherepashchuk, R. Sunyaev, S. Molkov +3
Based on multiyear INTEGRAL observations of SS433, a composite IBIS/ISGRI 18-60 keV orbital light curve is constructed around zero precessional phase . It shows a peculi…
The Mass of the Compact Object in the X-Ray Binary Her X-1/HZ Her
M. K. Abubekerov, E. A. Antokhina, A. M. Cherepashchuk +1
We have obtained the first estimates of the masses of the components of the Her X-1/HZ Her X-ray binary system taking into account non-LTE effects in the formation of the H_gamma a…
The Mass of the Compact Object in the Low-Mass X-ray Binary 2S 0921-630
M. K. Abubekerov, E. A. Antokhina, A. M. Cherepashchuk +1
We interpret the observed radial-velocity curve of the optical star in the low-mass X-ray binary 2S 0921-630 using a Roche model, taking into account the X-ray heating of the optic…
Analysis of Light Curves of Eclipsing Systems with Exoplanets: HD 189733
M. K. Abubekerov, N. Yu. Gostev, A. M. Cherepashchuk
High-accuracy multicolor light curves of the binary system HD 189733, which contains an exoplanet, are analyzed. We have determined the radii of the star and the planet in the bina…
