The open cluster NGC 5662 and its neighboring cepheid V Centauri

Abstract

Based on new photometric and kinematical data the structure and stellar composition of the open cluster NGC 5662 is examined. The presence of differential reddening across the cluster field is detected and the cluster stability examined. The luminosity function, distance, age, and chemical composition of NGC 5662 are determined from photometric and spectroscopic data. The new astrophysical parameters derived support the conclusion that the Cepheid V Cen (P=5.5 days) is very likely a cluster member. The UBV, DDO, CMT1T2 observations and the detailed results obtained in this work have been recently published by Clariá et al. (1991).
