Variable stars in the field of the open cluster NGC 7789.

JAHN K., KALUZNY J. and RUCINSKI S.M.

Abstract (from CDS):

Fifteen variable stars have been discovered during four nights of monitoring of NGC 7789. It was possible to determine periods for ten of these variables. Seven objects are W UMa-type binaries, in this number five are members of the cluster. Among the remaining variables, there are three further close binaries, one δ Scuti which is a blue straggler in the cluster, and one multi-modal variable (with indeterminable periods). One of the binaries showed an eclipse-like event; this binary is a good candidate for determination of masses of its components at the turn-off point of the cluster.
