The pulsating extreme helium star BD + 1303224 (V652 Her)
Description
New radial velocity data for the pulsating extreme helium star V652Her (BD + 1303224) have been obtained with a time resolution of 100 s. High-frequency structure in the radial velocity curve is detected, and a comparison with previous data suggests that the detailed shape of the velocity curve is variable. The data imply that the effective surface gravity must increase by a factor of 4 at minimum radius. (author)
