VW LMi: tightest quadruple system known. Light-time effect and possible secular changes of orbits
T. Pribulla, D. Baludansky, P. Dubovsky +4
Tightest known quadruple systems VW LMi consists of contact eclipsing binary with P_12 = 0.477551 days and detached binary with P_34 = 7.93063 days revolving in rather tight, 355.0…
Optical flare activity in the low-mass eclipsing binary GJ~3236
S. Parimucha, P. Dubovsky, M. Vanko +1
We present our observations of the low-mass eclipsing binary GJ~3236. We have analyzed a phased light-curve and confirmed previously determined fundamental parameters of the…
Spin-period variations in the intermediate polar RX J2133.7+5107
V. Breus, I. L. Andronov, P. Dubovsky +3
We report the results of long-term time series photometry on RX J2133.7+5107 (also known as 1RXS J213344.1+510725) obtained at several observatories. Using data taken during 17 yea…
Variability of the Spin Period of the White Dwarf in the Intermediate Polar V405 Aur: Low-Mass Third Body or Precession ?
V. V. Breus, I. L. Andronov, P. Dubovsky +9
We present the results of photometric CCD observations of the magnetic cataclysmic variable V405 Aurigae (RX J0558.0+5353 = 1RXS J055800.7+535358) obtained using different instrume…

We present new multicolour (UBVRcIc) photometric observations of classical symbiotic stars, EG And, Z And, BF Cyg, CH Cyg, CI Cyg, V1329 Cyg, TX CVn, AG Dra, Draco C1, AG Peg and A…
New photometric observations of the transiting extrasolar planet TrES-3b
M. VaÅko, M. JakubÃk, T. KrejÄová +7
We present new transit observations of the transiting exoplanet TrES-3b obtained in the range 2009 -- 2011 at several observatories. The orbital parameters of the system were redet…
On the spin and orbital variability of the intermediate polars
V. Breus, I. L. Andronov, P. Dubovsky +2
We present a review of the results of long-term photometric monitoring of selected magnetic cataclysmic binary systems, which belong to a class named "Intermediate polars". We foun…
Photometric Analysis of Recently Discovered Eclipsing Binary GSC 00008-00901
S. Parimucha, T. Pribulla, M. VaÅko +2
Photometric analysis of light curves of newly discovered eclipsing binary GSC 0008-00901 is presented. The orbital period is improved to 0.28948(11) days. Photometric param…
ASASSN-18fk: A new WZ Sge-type dwarf nova with multiple rebrightenings and a new candidate for a superhumping intermediate polar
E. Pavlenko, K. Niijima, P. Mason +23
We present the result of a multi-longitude campaign on the photometric study of the dwarf nova ASASSN-18fk during its superoutburst in 2018. It was observed with 18 telescopes at 1…
