Simultaneous Light Curve, Color Curve and Line Profile Fitting for Pulsating Stars

Abstract

In recent years pulsating stars in the lower part of cepheid instability, e.g. δ scuti and γ doradus stars, have been indicated as good laboratories to sound stellar interior through a seismological approach. The most relevant amount of data about pulsating stars derives from light curves, colour curves and photospheric absorption line profiles. Once outlined the relations of such observables with fundamental pulsational models, we review the most used principles and techniques to work out some seismological information from these data.
