Phase-Resolved Spectroscopy of the Polar V379 Vir with a Brown Dwarf
M. V. Suslikov, A. I. Kolbin, N. V. Borisov
The polar V379 Vir is a well-known magnetic cataclysmic variable with a brown dwarf donor. Despite numerous studies of this system across various spectral ranges, a detailed invest…
The Optical Study of the Eclipsing Polar SDSS J002637.06+242915.6
V. Yu. Kochkina, A. I. Kolbin, T. A. Fatkhullin +2
We have analyzed phase-resolved photometric and spectroscopic observations of the eclipsing polar SDSS J002637.06+242915.6. The light curve has a M-shaped bright phase that was rep…
On accretion in the polar V379 Vir
M. V. Suslikov, A. I. Kolbin, N. V. Borisov
Based on optical and infrared survey data spanning years of observations, the long-term variability of the polar V379 Vir with a brown dwarf secondary has been studied…
An X-ray and Optical Study of the Dwarf Nova Candidate OGLE-BLG-DN-0064
A. B. Sibgatullin, V. I. Dodon, I. I. Galiullin +3
The source OGLE-BLG-DN-0064 (hereafter OGLE64) was classified as a potential dwarf nova based on its regular outburst activity revealed by the OGLE optical survey. In this paper, w…
Gaia 19cwm -- an eclipsing dwarf nova of WZ Sge type with a magnetic white dwarf
A. I. Kolbin, T. A. Fatkhullin, E. P. Pavlenko +6
The spectral and photometric studies of the cataclysmic variable Gaia 19cwm (or ZTF19aamkwxk) have been performed. Based on the analysis of long-term variability, it is concluded t…
