Light and line profile variations due to r-mode pulsations. With an application to the ZZ Ceti star G117-B15A. (1986). Revista Mexicana De Astronomía Y Astrofísica, 12(1), 343. https://astronomia.unam.mx/journals/rmxaa/article/view/1986rmxaa..12..343k
Abstract
We present a general formulation for the effects of r-mode nonradial pulsations on the light curves and line profiles of a slowly rotating star, given a pulsation model and model atmospheres. We show that the temperature perturbation, the gravity perturbation and the light variations are proportional to the spheroidal component of the displacement, while the velocity perturbation is proportional to the toroidal component. Therefore, when calculating the observable effects of r-mode pulsations, it is necessary to include both the toroidal and spheroidal components of the displacement in the calculations.Similar Articles
