|Title||X-ray emission from high-mass young stellar objects in M17|
|Author||Dr Gregor Rauw|
|Description||We propose to observe the star forming region M17 for 30 ksec with XMM. These observations will allow us to study the properties of the X-ray emission of a sample of massive Class 1 YSOs. These data will help us understand the origin of the hard (kT = 3 keV) X-ray emission from massive YSOs and will provide valuable information on the possible existence of a hot corona during this evolutionary phase, prior to the onset of the powerful stellar winds. The requested XMM data will also allow us to study the incidence of variability among high-mass YSOs. A detailed investigation of the X-ray emission from massive YSOs in M17 should therefore help us to constrain the role of disks, magnetic fields and mass-loss in the early evolution of massive stars.|

|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.
