We propose to observe the star forming region M17 for 30 ksec with XMM. Theseobservations will allow us to study the properties of the X-ray emission ofa sample of massive Class 1 YSOs. These data will help us understand the originof the hard (kT = 3 keV) X-ray emission from massive YSOs and will providevaluable information on the possible existence of a hot corona during thisevolutionary phase, prior to the onset of the powerful stellar winds. Therequested XMM data will also allow us to study the incidence of variabilityamong high-mass YSOs. A detailed investigation of the X-ray emission frommassive 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 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.
