Quasiperiodic patterns in $\delta$ Scuti stars: an in-depth study of the CoRoT star HD 174966

Abstract

In this work, we have gone one step further from the study presented in the first CoRoT symposium. Our analysis consists on constructing a model database covering the entire uncertainty box of the $\delta$ Sct star HD174966, derived from the usual observables ($\mathrm{T}_{\mathrm{eff}}$, $\log g$ and [Fe/H]), and constraining the models representative of the star. To do that, we use the value of the periodicity (related to $\Delta\nu_{\ell}$) found in its CoRoT pulsating spectrum.
