  • Analysis of cataclysmic variable GSC02197-00886 evolution 
    Mitrofanova A.; Borisov N.; Shimansky V. (2014)
    We present the spectral analysis of the physical state and evolution of the WZSge-type cataclysmic variable GSC02197-00886. The spectra of the system, covering the total orbital period at the time of the outburst on May ...
  • On the formation of TW Crv optical radiation 
    Shimansky V.; Mitrofanova A.; Borisov N.; Fabrika S.; Galeev A. (2016)
    © 2016, Pleiades Publishing, Ltd.We present the analysis of the optical radiation of the young pre-cataclysmic variable TW Crv. Spectroscopic and photometric observations were obtained at the SAO RAS 6-m BTA telescope and ...
  • PN G068.1+11.0: A young pre-cataclysmic variable with an extremely hot primary 
    Mitrofanova A.; Shimansky V.; Borisov N.; Spiridonova O.; Gabdeev M. (2016)
    © 2016, Pleiades Publishing, Ltd.An analysis of spectroscopic and photometric data for the young pre-cataclysmic variable (PCV) PN G068.1+11.0, which passed through its common-envelope stage relatively recently, is presented. ...
  • Research on the HIP 18856 binary system 
    Efremova P.; Mitrofanova A.; Dyachenko V.; Beskakotov A.; Maksimov A.; Rastegaev D.; Balega Y.; Komarinsky S. (2021)
    The results of a study on the binary HIP 18856 and construction of its orbit are presented. New observational data were obtained at the BTA of SAO RAS in 2007-2019. Earlier, Cvetković et al. constructed the orbit for this ...
  • The intermediate-age pre-cataclysmic variables SDSS J172406+562003 and RE J2013+4002 
    Shimansky V.; Borisov N.; Nurtdinova D.; Mitrofanova A.; Vlasyuk V.; Spiridonova O. (2012)
    We have analyzed the physical status of the pre-cataclysmic variables SDSSJ172406+562003 and RE J2013+4002, which have evolved after their common-envelope stage a time t = 10 6-10 7 years. Spectroscopy and photometry of ...
