Abstract

New BVRI light curves of the eclipsing binary BG Peg were obtained and analysed using the Wilson-Devinney code. The observations (102 hours during a span of 108 days) were collected to perform an accurate frequency analysis of the pulsations of the primary component of the system, which is of δ Sct type. Three pulsation frequencies were identified in that star.
