V/43 CATALOGUE OF MASSES AND AGES OF STARS IN TWELVE OPEN CLUSTERS ================================================================================ MYAKUTIN V.I., RAM SAGAR JOSHI U.C.: 1984 Bull. Inform. CDS 26, 103 ================================================================================ Description: In this catalogue the evolutionary masses and ages of about 1030 stars in 12 open clusters for which the UBV photoelectric photometry has been carried out at the U.P. State Observatory, Nainital, India are listed. The mass and age of a star can be estimated by its position in the H-R diagram using the theoretical evolutionary tracks of stars with different masses. In comparison to field stars, members of an open cluster are more suitable objects for such calculations because of the homogeneous chemical composition in the clusters and the reliability of luminosities and temperatures determined from the cluster UBV data (Piskunov, 1980) See the list of clusters in the Note(1) below.
