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…
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…
