| Abstract | We propose to observe the core of the extremely young cluster Cyg OB2. Thiscluster contains 3 very massive X-ray bright O-type stars known to display avariable non-thermal radio emission. By simultaneously monitoring these stars with XMM, the VLA and optical spectroscopy, and by combining these data withforthcoming INTEGRAL data we will be able to obtain unprecedented information on the still mysterious origin of relativistic particles in the stellar winds of early- type stars. The requested XMM observations will further provide thedeepest yet X-ray survey of this region which is believed to harbour a very young globular cluster containing more than 100 O-stars therefore providinginformation on the earliest phases of star formation in high-density clusters. |

| 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. |
