Study of variable stars associated with maser sources: G025.65+1.05
A. M. Sobolev, A. P. Bisyarina, S. Yu. Gorda +1
We report variation of K-band infrared (IR) emission in the vicinity of the G025.65+1.05 water and methanol maser source. New observational data were obtained with 2.5m telescope o…
Analysis of colour and polarimetric variability of RW Aur A in 2010-2018
A. Dodin, K. Grankin, S. Lamzin +6
Results of photometry and polarimetry of a young star RW Aur A observed during unprecedented long and deep (up to mag) dimming events in 2010-11 a…
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…
Spectroscopic and photometric observations of Symbiotic Nova PU Vul during 2009-2016
A. A. Tatarnikova, M. A. Burlak, E. A. Kolotilov +5
A new set of low-resolution spectral and UBVJHKL-photometric observations of the symbiotic nova PU Vul is presented. The binary has been still evolving after the symbiotic nova out…
