The Radial Velocity Curve of V652 Her (BD+13°3224)
Published online by Cambridge University Press: 12 April 2016
Abstract
New radial velocity data for the pulsating extreme helium star V652 Her (BD+13°3224) 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.
