Photometric binary content in intermediate/old open clusters.

SANDHU T.S., PANDEY A.K. and SAGAR R.

Abstract (from CDS):

The stellar evolutionary models by Bertelli et al. (1994A&AS..106..275B) have been used to generate synthetic colour-magnitude diagrams (CMDs) of open clusters. A comparison of the synthetic integrated luminosity function (ILF) and synthetic colour distribution with the corresponding observed distributions is used to estimate the photometric binary content in three intermediate age open clusters, which is found to be about 30% in these clusters.
