On Asteroseismic Constraints for Modelling the δ Scuti Stars V480 Tau and θ2 Tau A

We investigate the structure and evolution of δ Scuti stars and discuss how basic properties as well as global oscillation frequencies are modified by moderate rotation. We present theoretical analyses of V480 Tau, observed during the MUSICOS 1996 campaign (Hao et al. 2001), and of θ² Tau A, monitored by the WIRE satellite (Poretti et al. 2002). We compare the observed spectra of frequencies with the theoretical oscillation frequencies calculated by including rotational effects.
