(Кинематика и физика небесных тел, 2001)
    The results of photometric studies of the flare star EV Lac obtained in the course of cooperative observations in 1998 are presented. No significant brightness variations in IR were found from simultaneous observations of ...
  • What limits the precision of ground-based stellar photometry and positional measurements? 
    Zhilyaev, B.E.; Romanyuk, Ya.O.; Verlyuk, I.A.; Svyatogorov, O.A.; Lovkaya, M.N. (Кинематика и физика небесных тел, 2005)
    Nobody has reached the photometric precision better than 0.001 of a magnitude with ground-based telescopes. At the same time, we should spend barely some seconds of time to detect a million photons from any bright star and ...
