Apparent motion of the circumstellar envelope of CQ Tau in scattered light
Boris Safonov, Ivan Strakhov, Maria Goliguzova +1
The study of spiral structures in protoplanetary disks is of great importance for understanding of processes in the disks, including planet formation. Bright spiral arms were detec…
Activity of (6478) Gault during January 13 - March 28, 2019
Oleksandra Ivanova, Yuri Skorov, Igor Luk'yanyk +5
We present the results of photometric observations of active asteroid (6478) Gault performed at heliocentric distances from 2.46 to 2.30 au and geocentric distances from 1.79 to 1.…
Differential Speckle Polarimetry of Betelgeuse in 2019-2020: the rise is different from the fall
Boris Safonov, Alexandr Dodin, Marina Burlak +6
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 201…
Chemical composition of metal-poor stars in Coma Berenices ultra-faint dwarf galaxy as a proxy to individual chemical enrichment events
Tatyana Sitnova, Lyudmila Mashonkina, Andrey Tatarnikov +3
We present NLTE abundances and atmospheric parameters for three metal-poor stars ([Fe/H]<-2) in Coma Berenices ultra-faint dwarf galaxy (UFD). The derived results are based on new…
Night-sky brightness and extinction at Mt. Shatdzhatmaz
V. Kornilov, M. Kornilov, O. Voziakova +6
The photometric sky quality of Mt. Shatdzhatmaz, the site of Sternberg Astronomical Institute Caucasian Observatory 2.5 m telescope, is characterized here by the statistics of the…
Resolved photometry of the binary components of RW Aur
S. Antipin, A. Belinski, A. Cherepashchuk +11
Resolved UBVRI photometry of RW Aur binary was performed on November 13/14, 2014 during the deep dimming of RW Aur with a newly installed 2.5 meter telescope of the Caucasus observ…
