Abstract

Star counts were carried out for 50 open clusters up to B = 16 mag. The limiting radii and the number of stars for OSCs are obtained. The parameters of the King distribution for surface star densities in the clusters, the relaxation times, and the tidal radii of the clusters are determined as well. Estimates of the concentration of clouds near these clusters are obtained from radio astronomical observations of molecular clouds in the CO emission line.
