Probing the nature of possible open cluster remnants with the Southern Proper Motion Program.

Abstract (from CDS):

We discuss the nature of eleven Possible Open Cluster Remnants (POCRs) by using absolute proper motions from the Southern Proper Motion (SPM) Program 3 (Girard et al., 2004AJ....127.3060G) combined with near infrared photometry from 2MASS. The analysis is done by considering the distribution of stars in the Color-Magnitude and the Vector Point diagrams. We successfully probed the capabilities of the SPM catalog to detect a physical group by looking at the open cluster Blanco 1. However, within the uncertainties of the SPM3 catalog and basing on 2MASS photometry we conclude that only one - ESO 282SC26 - out of eleven objects turns out to be a probable physical group. We suggest it is an open cluster 1.3Gyr old and located 1.4kpc from the Sun.
