Be Stars in the Galactic Cluster M 52
Abstract
It is shown that the galactic cluster M 52 (NGC 7654) contains several emission-line B-type stars. Published photometry shows that these Be stars lie at positions in the cluster color-magnitude diagram where stars are still undergoing main-sequence core hydrogen burning. Key words: emission-line stars - galactic clusters - stellar evolutiQn
