BOAO photometric survey of Galactic open clusters. II. Physical parameters of 12 open clusters

摘要

We have initiated a long-term project, the BOAO photometric survey of open clusters, to enlarge our understanding of Galactic structure using UBVI CCD photometry of open clusters, which have been little studied before. This is the second paper of the project, in which we present the photometry of 12 open clusters. We have determined the cluster parameters by fitting the Padua isochrones to the color-magnitude diagrams of the clusters. All the clusters except for Be 60 and NGC 1348 are found to be intermediate-age to old (0.2-4.0 Gyrs) open clusters with a mean metallicity of Fe/H approximate to 0.0. References: 23
