Scientific paper

This paper reports on the fifth STEPHI multi-site photometric campaign in 1993 devoted to the δ Scuti star BDS 1269A (VW Ari). The observation yielded a data set of 150.7 hours. Our analysis has resulted in 7 identified frequencies. These frequencies exhibit three couple-frequency character, and also fit the previous investigations quite well. An attempt to identify the pulsation modes is made, but no equidistant evidence can be detected, and a second-order effect for rotational splitting has to be considered to explain the complicated nature of BDS 1269A.
