    Emily Brunsden (York University): Spectroscopic Mode Identification of Gamma Doradus Stars

    Asteroseismology is the study of pulsations in stars. Pulsations occur in most types of stars, in most times of their lives, but one type of pulsation, in some classes of star, offers something special. The pulsations in Doradus stars are non-radial g-modes, where the restoring force is gravity. The physical origin of the pulsations means the pulsations propagate very deep, probing the stellar interior. This talk will present the approach of spectroscopic time-series observations of the stars, how we characterise the multi-periodic variations and determine the surface geometry of the pulsation. With now a couple of dozen stars analysed in this way I will discuss early trends observed for main sequence pulsators and the future of this work as it complements the wealth of photometric observations.
