Chandra OBSERVATIONS OF THE OPEN CLUSTER

Our analysis of Chandra X-ray Observatory data for the open cluster NGC 2516, sometimes referred to as "the southern Pleiades", has yielded over 150 X-ray detections in both HRC and ACIS images of the central region of the cluster. We identify some of the new X-ray sources with photometric cluster members and compare these new Chandra results with those of ROSAT. To date, 82 detected X-ray sources (42% of surveyed cluster members) are tentatively identified as cluster members. We also discuss the X-ray properties of late-type members in comparison with those of corresponding stellar types in the more metal rich approximately coeval Pleiades Cluster
