The search for δ Scuti stars in open clusters.

FRANDSEN S. and ARENTOFT T.

Abstract (from CDS):

In order to improve the tests of models of stellar evolution, observations giving tighter constraints on the models were initiated by the formation of an informal group STACC (Frandsen, 1992, Delta Scuti Star Newsletter Vienna Observatory 5, 12). The purpose of the group is to search for and make observations of δ Scuti stars in open clusters. This paper presents some of the results of the search, mainly for distant open clusters with a rich population of variables. Included is an announcement of a target list (Frandsen & Arentoft 1998, The Book, in prep.) and four examples of new Colour-Magnitude (CM) diagrams of open clusters considered to be interesting targets. Finally, we present the fruits of extensive searching: an open cluster that contains many δ Scuti stars.
