| Abstract | GT-X-ray emission from Early Type stars is still one of the most puzzlingaspects of stellar X-ray astronomy. None of the proposed models forexplaining the origin of the X-ray emission has been fully successful,whilst strong evidence of a richness of phenomena characterizing theatmoshperes of these stars comes from the recent ASCA observations. Wepropose a short (10,000 s) observation of Epsilon Ori to obtain amoderate resolutino spectrum with high statistics with EPIC and a highresolution, moderate statistics spectrum with RGS in order to gainsubstantial hints in the understanding of the physical phenomenaresponsible for the heating of the X-ray emitting regions. |

| 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. |
