The data mining: An analysis of 20 eclipsing binary light-curves observed by the INTEGRAL/OMC
P. Zasche
Twenty eclipsing binaries were selected for an analysis from a huge database of observations made by the INTEGRAL/OMC camera. The photometric data were processed and analyzed, resu…
Period changes in six contact binaries: WZ And, V803 Aql, DF Hya, PY Lyr, FZ Ori, and AH Tau
P. Zasche, A. Liakos, P. Niarchos +3
Six contact binaries lacking a period analysis have been chosen to search for the presence of a third body. The O-C diagrams of these binaries were analyzed with the least-squares…
The first light-curve analysis of eclipsing binaries observed by the INTEGRAL/OMC
P. Zasche
Three Algol-type binaries in Cygnus constellation were selected for an analysis from a huge database of observations made by the INTEGRAL/OMC camera. These data were processed and…
Multiple stellar systems under photometric and astrometric analysis
P. Zasche
The light-time effect method, its limitations and applications were studied. A powerful combined method of simultaneous analysis of the O-C diagrams and astrometric orbit in triple…
Combining astrometry with the light-time effect: The case of VW Cep, zeta Phe and HT Vir
P. Zasche, M. Wolf
Three eclipsing binary systems with astrometric orbit have been studied. For a detailed analysis two circular-orbit binaries (VW Cep and HT Vir) and one binary with an eccentric or…
Eclipsing Binaries with Possible Light-Time Effect
Zasche Petr, Zejda Miloslav, Brat Lubos
The period changes of six eclipsing binaries have been studied with focus on the light-time effect. With the least squares method we also calculated parameters of such an effect an…
