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…
Light curve solutions of the eccentric Kepler binaries KIC 11619964 and KIC 7118545 and mid-eclipse brightening of KIC 11619964
Diana Kjurkchieva, Doroteya Vasileva
We carried out light curve solutions of two eclipsing detached binaries on eccentric orbits observed by Kepler. The orbits and fundamental parameters of KIC 11619964 and KIC 711854…
Light Curve Solutions of Ten Eccentric Kepler Binaries, Three of them with Tidally Induced Humps
D. Kjurkchieva, D. Vasileva
We carried out light curve solutions of ten detached eclipsing eccentric binaries observed by Kepler. The formal errors of the derived parameters from the light curve solutions are…
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…
Light curve solutions of the ultrashort-period binaries
Diana Kjurkchieva, Dinko Dimitrov
We carried out light curve solutions of the ultrashort-period binaries with MS components observed by . All six targets turned out almost in thermal contact with contact or…
