A study of stellare population in the Orion cluster. The south vicinity of L 1642 dark cloud.
Abstract
A catalog of photoelectric UBVR1-prime photometry for 199 stars between 7 and 15 m V in the southern vicinity of the Orion cluster is presented. Forty-one possible cluster members, including 12 variables and IR sources as well as nine stars of early spectral classes from B5 to A5, are identified. Intermediate- and late-type stars up to +7 m M(V) that are close to the Main Sequence are also probable cluster members. Two-color diagrams and the H-R diagram do not exhibit any essential differences from the same diagrams in the central zone and close vicinities of the cluster.
