| Description | GT-The brightest star, optically and in X-rays, in the Orion Nebula is the OV star theta1 Ori C. It is a member of the Trapezium with mv=5.14. Young hot stars reveal strong stellar winds, as derived from optical-UV line profiles. The X-rays are thought to come from shocked stellar winds and can be either thermal, nonthermal, or both. With this observation, as part of a more extended program with O and WR stars, we will obtain a detailed X-ray spectrum to study the nature of this emission. This will give more insight in the origin of the X-ray source and about the location and the chemical composition of the hot gas in the stellar wind. Around theta1 Ori C, the Orion cluster contains hundreds of young and forming stars. We will study the complete field with the EPICs. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
