Survey for delta Sct components in eclipsing binaries and new correlations between pulsation frequency and fundamental stellar characteristics
Original language description
CCD observations of 68 eclipsing binary systems, candidates for containing delta Scuti components, were obtained. Their light curves are analysed using the (PERIOD)04 software for possible pulsational behaviour. For the systems QY Aql, CZ Aqr, TY Cap, WYCet, UW Cyg, HL Dra, HZ Dra, AU Lac, CL Lyn and IO UMa, complete light curves were observed due to the detection of a pulsating component. All of them, except QY Aql and IO UMa, are analysed with modern astronomical softwares in order to determine theirgeometrical and pulsational characteristics. Spectroscopic observations of WY Cet and UW Cyg were used to estimate the spectral class of their primary components, while for HZ Dra radial velocities of its primary were measured. O - C diagram analysis was performed for the cases showing peculiar orbital period variations, namely CZ Aqr, TY Cap, WY Cet and UW Cyg, with the aim of obtaining a comprehensive picture of these systems.
