International observational campaign of the 2014 eclipse of EE Cep
D. Pieńkowski, C. Gałan, T. Tomov +64
Context. EE Cep is one of few eclipsing binary systems with a dark, dusty disk around an invisible object similar to ε Aur. The system is characterized by grey and asymmetric eclip…
First observations with the 25 cm telescope of the Shumen Astronomical Observatory
Diana Kjurkchieva, Sunay Ibryamov, Borislav Borisov +3
The first observations with the 25 cm telescope of the Shumen Astronomical Observatory led to the following conclusions: (a) Intra-night observations of variable stars with an ampl…
Planet-star interactions with precise transit timing. I. The refined orbital decay rate for WASP-12 b and initial constraints for HAT-P-23 b, KELT-1 b, KELT-16 b, WASP-33 b, and WASP-103 b
G. Maciejewski, M. Fernández, F. Aceituno +11
Theoretical calculations and some indirect observations show that massive exoplanets on tight orbits must decay due to tidal dissipation within their host stars. This orbital evolu…
Observations and light curve solutions of ultrashort-period eclipsing binaries
Diana P. Kjurkchieva, Dinko P. Dimitrov, Sunay I. Ibryamov +1
Photometric observations in V and I bands and low-dispersion spectra of ten ultrashort-period binaries (NSVS 2175434, NSVS 2607629, NSVS 5038135, NSVS 8040227, NSVS 9747584, NSVS 4…
Stochastic modeling of multiwavelength variability of the classical BL Lac object OJ 287 on timescales ranging from decades to hours
A. Goyal, L. Stawarz, S. Zola +109
We present the results of our power spectral density analysis for the BL Lac object OJ\,287, utilizing the {\it Fermi}-LAT survey at high-energy -rays, {\it Swift}-XRT in X-rays…
Light curve solutions of 12 eccentric Kepler binaries and analysis of their out-of-eclipse variability
Diana Kjurkchieva, Doroteya Vasileva, Dinko Dimitrov
The eccentricity, periastron angle, orbital inclination, mass ratio, stellar temperatures and relative stellar radii of 12 eclipsing eccentric binaries were determined on the basis…
