NGC 7419: An open cluster rich in Be stars.

PIGULSKI A. and KOPACKI G.

Abstract (from CDS):

The results of our CCD photometric Hα observations of NGC 7419 are presented. The observations resulted in a discovery of 17 new Be stars and two other emission-line objects. In consequence, the number of known Be stars in this young cluster increased more than twofold and equals now to 31. This is at present the largest number of Be stars known in any galactic open cluster. Moreover, we estimate that these 31 Be stars constitute 36±7% of all cluster B-type stars brighter than RC=16.1mag. This locates NGC 7419 among these open clusters which are richest in Be stars such as galactic NGC 663, NGC 330 in SMC, and NGC 1818A in LMC.
