Observable quantities of nonradial pulsations in the presence of slowrotation.
Abstract
Theoretical power spectra of both light and radial velocity variations of a nonradially pulsating star that include the effects of rotation are presented. Three classes of motion are defined, depending on the symmetry of the mode of interest and its orientation with respect to the rotating axis. The use of tabulated model atmospheres to predict color variations is compared to the blackbody approximation for two cases, a hydrogen white dwarf (DA) and a main-sequence B Star.
