| Abstract | We propose a 530 ks X-ray survey of the population of young stars embedded inthe L1641 portion of the Orion A giant molecular cloud, the closest giantmolecular cloud to the Sun. In our existing Spitzer survey of this cloud, wehave found 140 protostars and 700 young stars with disks. The X--rayobservations are the premier method of identifying the remaining young starswithout disks. With these data we can study: 1) The relative importance ofclustered and isolated star formation 2) The effect of environment on starformation and disk evolution and 3) The evolution of the X-ray emitting plasmafrom the protostellar to pre-main sequence phase. |

| 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. |
