| Abstract | We have recently participated in an intense near-IR (NIR) monitoring campaign ofthe embedded star forming region Cygnus OB7. It has revealed the region is richin dynamic protostars, eruptive T Tauri stars and Class II objects. There areseveral newly discovered protostars which have shown multiple events of 3+magnitudes, with periodic and quasi-periodic variations on time scales of monthsand years. NIR classification can even change between observations. We seek two70 ks XMM observations to measure the X-ray luminosity of the known Class 0-IIsources including eruptive T Tauri stars as well as to identify new Class IIIsources in an extremely young active region. |

| 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. |
