Photometric Study and Search for Pulsations in RZ Dra and EG Cep
R. Pazhouhesh, A. Liakos, P. Niarchos
This paper presents CCD observations of the Algol-type eclipsing binaries RZ Dra and EG Cep. The light curves have been analyzed with the PHOEBE software and Wilson-Devinney code (…
DD Mon and XY UMa: CCD Photometry and modelling of two close binary systems with solar-type components
K. Gazeas, A. Liakos, P. Niarchos
We present our ground-based CCD observations of the close binary systems DD Mon and XY UMa in B, V, R and I bands. The light curves are analyzed using the Wilson-Devinney code (W-D…
The Algol type eclipsing binary X Tri: BVRI modelling and O-C diagram analysis
A. Liakos, P. Zasche, P. Niarchos
CCD photometric observations of the Algol-type eclipsing binary X Tri have been obtained. The light curves are analyzed with the Wilson-Devinney (WD) code and new geometric and pho…
Multi-ring structure of the eclipsing disk in EE Cep - possible planets?
C. Galan, M. Mikolajewski, T. Tomov +57
The photometric and spectroscopic observational campaign organized for the 2008/9 eclipse of EE Cep revealed features, which indicate that the eclipsing disk in the EE Cep system h…
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…
