  • High-frequency variations of hydrogen spectral lines in the B3V star η UMa 
    Pokhvala, S.M. (Advances in Astronomy and Space Physics, 2015)
    We reported the detection of high-frequency variations in the hydrogen Balmer lines in the hot star η UMa of spectral class B3V. Spectral observations of η UMa were carried out with slitless spectrograph (R ∼ 100) installed ...
  • High-speed multicolour photometry with CMOS cameras 
    Pokhvala, S.M.; Zhilyaev, B.E.; Reshetnyk, V.M. (Advances in Astronomy and Space Physics, 2012)
    We present the results of testing the commercial digital camera Nikon D90 with a CMOS sensor for high-speed photometry with a small telescope Celestron 11ʺ at the Peak Terskol Observatory. CMOS sensor allows to perform ...
  • Low-resolution spectroscopy of the chromospherically active stars 61 Cyg AB with small telescopes 
    Pokhvala, S.M.; Zhilyaev, B.E.; Reshetnyk, V.M.; Shavlovskij, V.I. (Advances in Astronomy and Space Physics, 2014)
    We carried out high-speed low-resolution spectroscopy of two stars, 61 Cyg A and B with small telescopes. They are known as chromospherically active stars of the K5V (A) and K7V (B) spectral types. These two stars are ...
  • Tests of commercial colour CMOS cameras for astronomical applications 
    Pokhvala, S.M.; Reshetnyk, V.M.; Zhilyaev, B.E. (Advances in Astronomy and Space Physics, 2013)
    We present some results of testing commercial colour CMOS cameras for astronomical applications. Colour CMOS sensors allow to perform photometry in three filters simultaneously that gives a great advantage compared with ...
