Pulsational content and abundance analysis of some Delta Scuti stars observed by CoRoT

TL;DR

This paper analyzes the pulsational behavior and chemical abundances of Delta Scuti stars observed by CoRoT, providing insights into their frequency spectra and stellar properties through combined space and ground observations.

Contribution

It offers the first abundance analysis of CoRoT-observed Delta Scuti stars and compares their frequency content with normal A-type stars, advancing understanding of their pulsation mechanisms.

Findings

Preliminary abundance patterns of Delta Scuti stars are presented.

Comparison reveals differences in frequency spectra between Delta Scuti and normal A-stars.

Insights into the origin of the large number of detected frequencies are discussed.

Abstract

Several Delta Sct stars were photometrically monitored with the satellite CoRoT and observed in high-resolution spectroscopy from ground. We present here the preliminary analysis of the abundance analysis of several potential CoRoT targets. Moreover, new insights are given about the problem of the huge number of detected frequencies by comparing Delta Sct stars with normal A-stars.
