Title A First X-ray View of Infrared Dark Clouds, Precursors to Star Clusters

Description A large population of infrared dark clouds (IRDCs) was recently discovered as a new component of the cold interstellar medium, inside which infrared and radio studies provide evidence for massive star formation. They are thought to represent the earliest phases of the formation of star clusters and massive stars. We propose to observe one of the closest massive IRDCs with XMM-Newton, as the first X-ray study of this new population of objects. This 84 ks EPIC observation of G053.11+00.05 will quantitatively measure the embedded stellar populations, especially the low mass stars that XMM-Newton effectively identifies. The goals are to evaluate the roles of IRDCs in the formation of star clusters and massive stars, and to constrain the current theories of clustered massive star formation.

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.
