Photometric study of a pulsating component in the eclipsing binary Y Cam.

Abstract (from CDS):

We present CCD photometric results of the eclipsing binary Y Cam, whose primary component has been known to be a δ Scuti type pulsator. Observations were performed for 16 nights, including two primary minima, from November 2000 to May 2001. After correction for light variations caused by the eclipsing phenomenon, we investigated its pulsating features in detail. We derived four pulsation frequencies of 15.0473c/d, 18.2852c/d, 14.8203c/d and 17.7348c/d using all data except for the primary eclipsing phase. The first frequency turned out to be constant over 40 years but the other frequencies have been changed or newly excited. It should be noted that V amplitude of the first frequency decreased to about a half in comparison with the previous results.
