Proper Motions, Membership, and Photometry of open Clusters Near ETA Carinae
Abstract
Proper motions and photographic photometry have been derived for nearly 600 stars with V between 7.5 and 15.5 in the region of the very young open clusters Tr 14, Tr 16, and Cr 232 based on 26 plates dating from 1893 to 1990. Cluster membership probabilities have been derived from the proper motions and color-magnitude diagrams of probable members of each cluster are presented. In contrast to a few of the previous studies we find all three clusters to lie at the same distance.
