Title Fossil sequential star formation in the CMa R1 region?

Description The CMa R1 region includes the arc-shaped ionized nebula S2-296, suggested to be an old supernova remnant, as well as several very young (less than 5 Myr) clusters. Based on archival ROSAT observations covering nearly 5 sq. deg. we have discovered a new, 10Myr old cluster that may be a fossil from a distinct, past star-formation episode, suggesting sequential star formation between supernova cavities. We propose a mosaic of 5 x 30ks EPIC fields to reveal a mixed population from both older and young clusters corresponding respectively to a fossil, and to an onging, star formation episode.

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.
