Chandra Observations of the Well-Studied 180 Myr Old Open Cluster M35
Abstract
M35 is a relatively close ( 800 pc), rich, young ( 180 Myr) open cluster which has been the focus of extensive multi-epoch spectroscopic and photometric study. Some 250 single and 100 binary stars ( 50 with orbits) are confirmed members and 310 have measured rotation periods. This detailed information about membership, binarity, and rotation, makes M35 an ideal target for studying not only the rotation-activity-age relation for cool stars, but also for the effect of a stellar companion on this relationship. We present preliminary results of a 130 ksec ACIS-I observation near the core of the M35, containing 180 cluster members. We explore how the coronal flux and temperature change across the cluster's color-period diagram, how binarity affects these results, and compare our findings with other clusters.
