We shortly present intermidiate results of a survey for weak magnetic fields among degenerate stars (white dwarfs and hot subdwarf stars). Kilogauss upper limits of longitudinal magnetic fields are presented for several brightest DA white dwarfs and

The behaviour of the General Magnetic Field of the Sun as a Star (GMFSS) is characterized by the change of amplitude of oscillations with the eleven-year cycle of activity. In maximum of activity GMFSS reaches its maximal values, and in a minimum rea

The results of spectropolarimetic study of one of the coolest Ap-stars Β CrB are presented. It was shown that effective magnetic fields measured in different spectral lines and folded in phase with the rotational period of the star significantly dif

We used the 0.5-m robotic telescope located at the Special Astrophysical Observatory of the Russian Academy of Sciences for monitoring two square degrees of the sky with the aim of detecting new exoplanets. A dimming of the visible brightness is expe
