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…
Period changes in six semi-detached Algol-type binaries
P. Zasche, A. Liakos, M. Wolf +1
Six semi-detached Algol-type binaries lacking a period analysis were chosen to test for a presence of a third body. The O-C diagrams of these binaries were analyzed with the least-…
Search for pulsation among suspected A-type binaries and the new multiperiodic Delta Scuti star HD217860
Yves Fremat, P. Lampens, P. Van Cauteren +9
We have explored a sample of suspected A-type binaries in a systematic way, both spectroscopically and photometrically. Due to their location in the H-R diagram, indications of pul…
Masses and angular momenta of contact binary stars
K. D. Gazeas, P. G. Niarchos
Results are presented on component masses and system angular momenta for over a hundred low-temperature contact binaries. It is found that the secondary components in close binary…
Resolving the pulsations of the subdwarf B star KPD 2109+4401
A. -Y. Zhou, M. D. Reed, S. Harms +8
We present the results of extensive time series photometry of the pulsating subdwarf B star KPD 2109+4401. Our data set consists of 29 data runs with a total length of 182.6 hours…
The double-mode nature of the HADS star GSC 00144-03031 and the Petersen diagram of the class
E. Poretti, J. C. Suarez, P. G. Niarchos +13
The double--mode pulsation of GSC 00144-03031 has been detected when searching for COROT targets. A very large dataset composed of 4722 photometric measurements was collected at si…
