Recently published episodic spectral (Levesque and Massey, 2020) and high angular resolution (Montarges et al, 2020) observations of Betelgeuse suggest that the deep minimum of 2019-2020 was caused by an enhanced dust abundance in the stellar atmosph

V CVn is a semiregular variable star with a V-band amplitude of $\approx2$ mag. This star has an unusually high amplitude of polarimetric variability: up to 6 per cent. It also exhibits a prominent inverse correlation between the flux and the fractio

FU Orionis is the prototype of a class of eruptive young stars (``FUors'') characterized by strong optical outbursts. We recently completed an exploratory survey of FUors using XMM-Newton to determine their X-ray properties, about which little was pr

Detailed monitoring of atmospheres of red supergiant stars is essential for the verification of physical models of mass loss. For such observations it is fundamentally important to employ methods resolving inhomogeneous stellar atmosphere. We present

Results of UBVRIJHKLM photometry and VRI polarimetry of a young star RW Aur A observed during 2010-11 and 2014-18 dimming events are presented. Polarization degree p of RWAur A at this period has reached 30 % in I band. As in the case of UXORs so cal
