The 32 Ori association: a test for the star formation history in our vicinity

We propose observations with XMMEPIC in two regions near Bellatrix (Gamma Ori).Both fields contain some weakline T Tauri type stars (WTTS) which have beenrecently recognized as members of a nearby (virgul100 pc) young (virgul25 Myr) stellarassociation. Our goal is to study the young stellar population in our vicinityin order to understand the star formation history of the solar neighbourhood.Particular goals for this proposal are: i) to detect the faintest Xray sourcesmembers of the association in those regions; ii) to study the Xray propertiesof the most conspicuous sources and characterize the sample in terms of coronalemission; iii) to compare the results with those obtained in field stars inorder to investigate the star formation history in the solar vicinity. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
