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

TL;DR

This study models the $ ext{HD 174966}$ $ ext{delta Scuti}$ star using CoRoT data, constructing a comprehensive model database to analyze its quasiperiodic pulsation patterns and constrain stellar parameters.

Contribution

It introduces a detailed modeling approach that incorporates the star's observed periodicity to better understand its pulsation characteristics.

Findings

Constructed a model database covering the star's uncertainty box.

Identified quasiperiodic patterns related to the star's pulsations.

Constrained stellar parameters using observed periodicity.

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.
