Missed 2020 Superoutburst of the Eclipsing WD-BD Cataclysmic Variable SDSS J1433+1011
D. V. Denisenko
Cataclysmic variable SDSS J143317.78+101123.3 with P=0.054241 d (78.1-min) was suspected to be a possible dwarf nova of WZ Sge type with the sub-stellar donor, but without detected…
Search for Nearby Ultracool Compact Binaries in Gaia DR2
D. V. Denisenko, I. Larin
The information contained in the Gaia Second Data Release (DR2) allows to search for the unusual objects with the pre-selected properties, literally constructing the stars with the…
MASTER OT J190519.41+301524.4: New Eclipsing Cataclysmic Variable of VY Scl Type
F. Martinelli, D. V. Denisenko
MASTER OT J190519.41+301524.4 was discovered as an optical transient of 15.7m by the Mobile Astronomical System of TElescope-Robots in March 2014. We report the results of photomet…
1RXS J161935.7+524630: New Polar with the Varying Accretion Modes on two Magnetic Poles
D. V. Denisenko, F. Martinelli
We report the discovery of a new cataclysmic variable DDE 32 identified with the ROSAT X-ray source 1RXS J161935.7+524630 in Draco. The variability was originally found by D. Denis…
Discovery of an unusual bright eclipsing binary with the longest known period: TYC 2505-672-1 / MASTER OT J095310.04+335352.8
V. Lipunov, E. Gorbovskoy, V. Afanasiev +16
We report on the MASTER Global Robotic Net discovery of an eclipsing binary, MASTER OT J095310.04+335352.8, previously known as unremarkable star TYC 2505-672-1, which displays ext…
Superoutburst of SDSS J090221.35+381941.9: First Measurement of Mass Ratio in an AM CVn-Type Object using Growing Superhumps
Taichi Kato, Tomohito Ohshima, Denis Denisenko +36
We report on a superoutburst of the AM CVn-type object SDSS J090221.35+381941.9 [J0902; orbital period 0.03355(6) d] in 2014 March-April. The entire outburst consisted of a precurs…
New Cataclysmic Variable 1RXS J161659.5+620014 in Draco
P. Balanutsa, D. Denisenko, E. Gorbovskoy +1
We report the discovery of a new cataclysmic variable MASTER OT J161700.81+620024.9 which is identical to the faint ROSAT X-ray source 1RXS J161659.5+620014. The object was observe…
New Cataclysmic Variable 1RXS J015017.0+375614 in Andromeda
A. Lazareva, N. Voroshilov, D. Denisenko +3
We report the discovery of a new cataclysmic variable in MASTER database which is identical to the faint ROSAT X-ray source 1RXS J015017.0+375614. The object was observed in outbur…
Study of the Cataclysmic Variable 1RXS J174320.1-042953
D. V. Denisenko, F. Martinelli
We report on the photometric analysis of the poorly studied cataclysmic variable in Ophiuchus 1RXS J174320.1-042953 (DDE 11). Results of the monitoring with the Bradford Robotic Te…
Cataclysmic Variables from USNO-B1.0 Catalog: Stars with Outbursts on Infrared Palomar Plates
D. V. Denisenko
The search was performed for cataclysmic variable stars with outlying infrared magnitudes in USNO-B1.0 catalog. The selection was limited to objects in the Northern hemisphere with…
Two New Cataclysmic Variables in Lyra
D. V. Denisenko
I report on the discovery of two cataclysmic variables in the same field in Lyra originally identified from their magnitudes in USNO-B1.0 catalogue and Palomar images. The historic…
New Cataclysmic Variable 1RXS J073346.0+261933 in Gemini
D. V. Denisenko, A. J. Drake, S. G. Djorgovski +3
In course of the search for the optical identifications associated with ROSAT X-ray sources we have found a highly variable object with the very unusual long-term behavior, color i…
