摘要
Several delta 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 delta Sct stars with normal A-type stars. (C) 2010 WILEY-VCH Verlag GmbH&Co. KGaA, Weinheim
