CCD photometry of distant open clusters. IV. Trumpler 5.

KALUZNY J.

Abstract (from CDS):

We present BVI photometry for Trumpler 5, a rich open cluster located in the Galactic anticenter. The cluster age is slightly lower than the age of M 67. Its distance modulus (m-M)0 and reddening E(B-V) are estimated at 12.4 and 0.58, respectively. These values were obtained for the assumed solar metallicity of the cluster. Our data indicate that Tr 5 is one of the richest objects among the sample of known old open clusters. The total mass included only in upper-main sequence stars exceeds 3000m☉. The angular diameter of the cluster is estimated at 11.6arcmin, which corresponds to a linear size of about 20pc for an estimated distance d≃3.0kpc.
