|Title||Probing Environmental Effect on CIrcumstellar Disk Evolution: the W3,W4 complex|
|Author||Dr Jinyoung Serena Kim|
|Description||We propose XMM-EPIC & Chandra-ACIS-I observations for the W3,W4 star forming regions to study circumstellar disk evolution in a high radiation environment. Multi-wavelength studies are necessary to obtain unbiased samples of young stars for statistical analysis: IR excess emission identifies stars with disks while X-rays help find diskless young stars. A candidate birth place of our Solar System is a high radiation environment in the vicinity of massive stars. We are testing the hypothesis that planetary systems like our own commonly form in such high radiation environment. With the unbiased sample of young stars from the proposed observations combined with what we have obtained, we will determine disk frequency as a function of mass and age, and will compare them with different environments.|

|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.
