Follow-up photometry of TrES-3
M. Vanko, G. Maciejewski, M. Jakubik +7
We present new observations of the transiting system TrES-3 obtained from 2009 to 2011 at several observatories. The orbital parameters of the system were re- determined and a new…
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…
SPHOTOM -- Package for an Automatic Multicolour Photometry
S. Parimucha, M. Vanko, P. Miklos
We present basic informations about package SPHOTOM for an automatic multicolour photometry. This package is in development for a creation of photometric pipe-line, which we plan t…
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…
Instabilities in Interacting Binary Stars
Ivan L. Andronov, K. D. Andrych, K. A. Antoniuk +43
The types of instability in the interacting binary stars are reviewed. The project "Inter-Longitude Astronomy" is a series of smaller projects on concrete stars or groups of stars.…
Multiwavelength evidence for a 15-year periodic activity in the symbiotic nova V1016 Cygni
S. Parimucha, D. Chochol, T. Pribulla +2
The ~15.1 years period found in the long-term UBV photoelectric and photographic photometry of the symbiotic nova V1016 Cyg is detected also in the (J-K) colour index and in the UV…
Period variations of Algol-type eclipsing binaries AD And, TW Cas and IV Cas
S. Parimucha, P. Gajdos, V. Kudak +2
We present new analysis of O-C diagrams variations of three Algol-type eclipsing binary stars AD And, TW Cas and IV Cas. We have used all published minima times (including visual a…
