We propose XMM/EPIC & Chandra/ACIS-I observations for the W3,W4 star formingregions to study circumstellar disk evolution in a high radiation environment.Multi-wavelength studies are necessary to obtain unbiased samples of young starsfor statistical analysis: IR excess emission identifies stars with disks whileX-rays help find diskless young stars. A candidate birth place of our SolarSystem is a high radiation environment in the vicinity of massive stars. We aretesting the hypothesis that planetary systems like our own commonly form in suchhigh radiation environment. With the unbiased sample of young stars from theproposed observations combined with what we have obtained, we will determinedisk frequency as a function of mass and age, and will compare them with different environments.

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.
