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…
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…
SDSS J085414.02+390537.3 -- a new asynchronous polar
A. I. Kolbin, M. V. Suslikov, V. Yu. Kochkina +3
The asynchrony of the polar SDSS~J085414.02+390537.3 was revealed using the data of ZTF photometric survey. The light curves show a beat period ~days. Duri…
Optical study of the polar BM CrB in low accretion state
A. I. Kolbin, N. V. Borisov, A. N. Burenkov +3
This paper presents a spectral and photometric study of the poorly studied polar BM CrB. Three states of the polar brightness and signs of transition from one-pole to two-pole accr…
On accretion in the eclipsing polar BS Tri
A. I. Kolbin, N. V. Borisov, N. A. Serebriakova +4
We analyze spectroscopic and photometric observations of the eclipsing polar BS Tri. The polar's light curve shape variations can be interpreted by changing contributions of the ac…
SRGe2149+6736 -- the new candidate to AM~Her type variables discovered by eROSITA telescope on "Spectrum--Roentgen--Gamma" orbital observatory
I. F. Bikmaev, A. I. Kolbin, V. V. Shimansky +18
We present the results of the optical identification, classification, as well as analysis of photometric and spectral observations of the X-ray transient SRGe2149+6736 detected by…
