Özet
In this study, 23 Algol-type binary systems, which were selected as candidate binaries with pulsating components, were observed at the canakkale Onsekiz Mart University Observatory. One of these systems was BG Peg. Its hotter component shows delta Scuti-type light variations. Physical parameters of BG Peg were derived from modelling the V light curve using the Wilson-Devinney code. The frequency analysis shows that the pulsational component of the BG Peg system pulsates in two modes with periods of 0.039 and 0.047 d. Mode identification indicates that both modes are most likely non-radial l = 2 modes.
