Abstract
The results of nine CCD photometric observing runs on KPD 0629-0016 are presented. During six of the runs measurements were obtained alternately through B and V filters. Four periodicities, for which there is good agreement between the frequencies identified in the B and V data, were extracted: these lie in the range 46-81 min. A fifth lower frequency appears to be definitely present, but is very uncertain due to aliasing. The ratios of the mode amplitudes measured in B and V, and the phase differences between variations in the two colours, are compatible with pulsation theory.
