  • Aperiodic optical variability of intermediate polars-cataclysmic variables with truncated accretion disks 
    Revnivtsev M.; Burenin R.; Bikmaev I.; Kniazev A.; Buckley D.; Pretorius M.; Khamitov I.; Ak T.; Eker Z.; Melnikov S.; Crawford S.; Pavlinsky M. (2010)
    We study the power spectra of the variability of seven intermediate polars containing magnetized asynchronous accreting white dwarfs, XSS J00564+4548, IGR J00234+6141, DO Dra, V1223 Sgr, IGR J15094-6649, IGR J16500-3307 ...
  • Broad band variability of SS433: Accretion disk at work? 
    Revnivtsev M.; Fabrika S.; Abolmasov P.; Postnov K.; Bikmaev I.; Burenin R.; Pavlinsky M.; Sunyaev R.; Khamitov I.; Sakhibullin N. (2006)
    We present broad band power spectra of variations of SS433 in radio, optical and X-ray spectral bands. We show that at frequencies lower than 10 -5 Hz the source demonstrates the same variability pattern in all these bands. ...
  • First simultanous X-ray and optical observations of rapid variability of supercritical accretor SS433 
    Revnivtsev M.; Burenin R.; Fabrika S.; Postnov K.; Bikmaev I.; Pavlinsky M.; Sunyaev R.; Khamitov I.; Aslan Z. (2004)
    We present results of first simultaneous optical and X-ray observations of peculiar binary system SS433. For the first time, chaotic variability of SS433 in the optical spectral band (R band) on time scales as small as ...
