| Abstract: |
Some new times of light maxima for three δ Scuti stars -- CY Aqr, BS Aqr and AD CMi -- have been determined based on new photoelectric photometry. Incorporated with the times presented in the literature, the O-C method is used to study the period variations of these stars with a newly-developed program OMC. The results reveal that for these three stars, the binary hypothesis concerning a low mass companion is reasonable in explaining the O-C diagrams. |
