Scientific paper

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 High-Resolution Camera and Advanced CCD Imaging Spectrometer 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.
