|Title||A Survey of Orion A with XMM and Spitzer: SOXS|
|Author||Dr Scott Wolk|
|Description||We propose a 530 ks X-ray survey of the population of young stars embedded in the L1641 portion of the Orion A giant molecular cloud, the closest giant molecular cloud to the Sun. In our existing Spitzer survey of this cloud, we have found 140 protostars and 700 young stars with disks. The X--ray observations are the premier method of identifying the remaining young stars without disks. With these data we can study: 1) The relative importance of clustered and isolated star formation 2) The effect of environment on star formation and disk evolution and 3) The evolution of the X-ray emitting plasma from the protostellar to pre-main sequence phase.|

|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.
