Pulsational content and abundance analysis of some δ Scuti stars observed by CoRoT
Abstract
Several δ Sct stars were photometrically monitored with the satellite CoRoT and observed in high-resolution spectroscopy from ground. We present here the preliminary results 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 δ Sct stars with normal A-type stars.
The CoRoT space mission was developed and is operated by the French space agency CNES, with participation of ESA's RSSD and Science Programmes, Austria, Belgium, Brazil, Germany, and Spain. This work is based on observations made with ESO Telescopes at the La Silla Observatory under the ESO Large Programmes LP 178.D-0361, LP 182.D-0356, and LP 185.D-0056.- Publication:
