Abstract

Space missions have produced an incredibly large database on pulsating stars. The light curves via the frequency content contain a detailed description of each star. The critical point is the identification of modes, especially in the non-asymptotic regime. The best derived parameters from the frequency content of a pulsating star light curve are the frequency differences and ratios. This presentation focuses on the potential of period ratios in mode identification.
