| Abstract | We propose observations with XMM-EPIC in two regions near Bellatrix (Gamma Ori).Both fields contain some weak-line T Tauri type stars (WTTS) which have beenrecently recognized as members of a nearby (~100 pc) young (~25 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 X-ray sourcesmembers of the association in those regions; ii) to study the X-ray 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. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
