[47.10] X-Ray Emission from the Ursa Major Group Detected in the ROSAT All Sky Survey

R.A. Stern (LMSAL), J.H.M.M. Schmitt (U. Hamburg), W. Voges (MPE), J.R. Stauffer (SAO)

We discuss the X-ray properties of members of the Ursa Major Moving Group detected in the ROSAT All Sky Survey (RASS). More than 80% of the solar-type (F8-G8) UMa Group members or candidates listed by Montes et al. are seen in the RASS data. We will compare the X-ray luminosities of the UMa Group (age ~ 300 Myr) with those of other young clusters, and examine the issues of group membership and possible contamination by young field stars in the detected sample.
