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…
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…
Spectroscopic and photometric study of the new eclipsing polar Gaia23cer
A. I. Kolbin, E. P. Pavlenko, V. Yu. Kochkina +11
We present the results of the optical study of the new eclipsing polar Gaia23cer. We analyzed the brightness variability of the polar in high ($\langle r \rangle \approx 16.5\mathr…
