  • Coordinated integral and optical observations of SS433 
    Cherepashchuk A.; Sunyaev R.; Fabrikat S.; Molkov S.; Barsukova E.; Antokhina E.; Irsmambetova T.; Panchenko I.; Postnov K.; Seifina E.; Shakura N.; Timokhin A.; Bikmaev I.; Sakhibullin N.; Gnedin Y.; Arkharov A.; Larionov V. (2004)
    Results of simultaneous INTEGRAL and optical observations of galactic microquasar SS433 in May 2003 are presented. The analysis of the X-ray and optical eclipse duration and hard X-ray spectra obtained by INTEGRAL together ...
  • INTEGRAL observations of SS433: Results of a coordinated campaign 
    Cherepashchuk A.; Sunyaev R.; Fabrika S.; Postnov K.; Molkov S.; Barsukova E.; Antokhina E.; Irsmambetova T.; Panchenko I.; Seifina E.; Shakura N.; Timokhin A.; Bikmaev I.; Sakhibullin N.; Aslan Z.; Khamitov I.; Pramsky A.; Sholukhova O.; Gnedin Y.; Arkharov A.; Larionov V. (2005)
    Results of simultaneous INTEGRAL and optical observations of the galactic microquasar SS433 in May 2003 and INTEGRAL/RXTE observations in March 2004 are presented. Persistent precessional variability with a maximum to ...
  • Radial-velocity curves and theoretical spectral-line profiles of the components of low-mass close X-ray binary systems 
    Antokhina E.; Cherepashchuk A.; Shimanskii V. (2005)
    We present the results of calculations of theoretical absorption-line profiles and radial-velocity curves for optical components in X-ray binary systems. Tidal distortion of the optical star and X-ray heating by incident ...
  • The mass of the black hole in the X-ray binary LMC X-1 
    Abubekerov M.; Antokhina E.; Gostev N.; Cherepashchuk A.; Shimansky V. (2016)
    © 2016, Pleiades Publishing, Ltd.A dynamical estimate of the mass of the black hole in the LMC X-1 binary system is obtained in the framework of a Roche model for the optical star, based on fitting of the He I 4471 Å and ...
  • The mass of the compact object in the low-mass X-ray binary 2S 0921-630 
    Abubekerov M.; Antokhina E.; Cherepashchuk A.; Shimanskii V. (2006)
    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 optical star and screening of X-rays coming ...
  • The mass of the compact object in the X-ray binary her X-1/HZ her 
    Abubekerov M.; Antokhina E.; Cherepashchuk A.; Shimanskii V. (2008)
    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 γ absorption line: m x = 1.8 M⊙ and mv = 2.5 M⊙. ...
