|Title||X-ray Follow-up to the Deep NIR Monitoring Campaign of CygOB7|
|Author||Dr Scott Wolk|
|Description||We have recently participated in an intense near-IR (NIR) monitoring campaign of the embedded star forming region Cygnus OB7 covering over 100,000 stars brighter than K=20. It has revealed the region is rich in protostars, eruptive T Tauri stars and ClassvirgulII objects. We have discovered periodic and aperiodic NIR variability seen among the Class I and Class II objects, indicative of variable accretion and quasi-instability of the inner hole. Further, NIR ..Class. can change between observations. We seek a 80virgulks XMM-Newton observation to compare X- ray luminosity to NIR variability of the known Class 0-II sources, eruptive T Tauri stars and eclipsing binaries as well as to identify new ClassvirgulII and Class III sources in a very young active region.|

|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.
