| Abstract |
Previous studies of the X-ray population of globular clusters revealed a relation between the number of X-ray sources and the encounter frequency of the cluster, pointing to a dynamical history for the sources. In order to extend this relationship to clusters of lower masses, we observed 8 rich open clusters using the XMM-Newton Observatory. We present preliminary results of the first X-ray study of the young rich open cluster M35. In order to classify the X-ray sources, we matched the XMM-Newton data with optical photometry and spectroscopy from the WIYN Open Cluster Study (WOCS). We found 51 X-ray sources in the field of M35 to a luminosity limit of 1030 ergs/s for cluster members. From the 21 optical counterparts, 3 sources are known spectroscopic binary systems, 9 are single stars, and 11 are still unclassified. 15 of the 21 sources are rapid rotators, suggesting a dynamo origin for the X-ray emission rather than dynamics. |
