Solution of newly observed transit of the exoplanet HAT-P-24b: no TTV and TDV signals
Diana Kjurkchieva, Dinko Dimitrov, Sunay Ibryamov
We present photometric observations of transit of the exoplanet HAT-P-24b using the Rozhen 2 m telescope. Its solution gives relative stellar radius r_{s}=0.1304 (a/R_{s}=7.669), r…
2MASSJ22560844+5954299: the newly discovered cataclysmic star with the deepest eclipse
D. Kjurkchieva, T. Khruzina, D. Dimitrov +3
Context: The SW Sex stars are assumed to represent a distinguished stage in CV evolution, making it especially important to study them. Aims: We discovered a new cataclysmic star a…
No variations in transit times for Qatar-1 b
G. Maciejewski, M. Fernández, F. J. Aceituno +11
The transiting hot Jupiter planet Qatar-1 b was presented to exhibit variations in transit times that could be of perturbative nature. A hot Jupiter with a planetary companion on a…
The unusual photometric variability of the PMS star GM Cep
E. Semkov, S. Ibryamov, S. Peneva +6
Results from UBVRI photometric observations of the pre-main sequence star GM Cep obtained in the period April 2011 - August 2014 are reported in the paper. Presented data are a con…
Light curve solutions of six eclipsing binaries at the lower limit of periods of the W UMa stars
Diana P. Kjurkchieva, Dinko P. Dimitrov, Sunay I. Ibryamov
Photometric observations in V and I bands of six eclipsing binaries at the lower limit of the orbital periods of W UMa stars are presented. Three of them are newly discovered eclip…
Ultrashort-period MS eclipsing systems. New observations and light curve solutions of six NSVS binaries
Dinko Dimitrov, Diana Kjurkchieva
We carried out photometric and low-resolution spectral observations of six eclipsing ultrashort-period binaries with MS components. The light curve solutions of the Rozhen observat…
