Recently, low-frequency periodic radio pulses have been detected from the prototypical M-dwarf flare star, UV Ceti. This shows that the low-frequency emission from this star is driven by auroral activ
M-type stars are the most common stars in the universe. They are ideal hosts for the search of exoplanets in the habitable zone (HZ), as their small size and low temperature make the HZ much closer in
The results of Cyg X-1 = HDE 226868/V1357 Cyg optical spectral monitoring in 2002-2004 are discussed. Spectral observations were carried out on Peak Terskol Observatory...
We propose INTEGRAL observations of theaccreting binary X-ray pulsar Her X-1 for a total of 460 ks in its Main-On state. The main goal is to answer a number of fundamental questions related to the cla
