Abstract

The effects of the geometric distortion of a rapidly rotating star on the relative amplitudes of radial velocity and luminosity variations are modeled. The possibility of determining the inclination angle of the rotation axis of a rapidly rotating star, from observations of its radial velocity and luminosity variations, is then explored and the nature of these effects for a model of an early B main-sequence star are presented. It is found that this approach holds sufficient promise that more detailed calculations should be embarked upon.
