Description An optical variability study of the benchmark star forming region NGC2264,
observed with CoRoT, suggests that the cluster is more extended than currently
believed. To confirm this result we obtained, in AO10, a 50ks EPIC pointing
toward the cluster periphery. The observation fully confirms the existence of a
spatially extended population. We propose to observe four more fields, each for
50ks. Our goals are: 1) establishing whether the clustered and dispersed
populations originated from the same or distinct star formation events; 2)
determining whether mass segregation affects NGC2264, thus compromising current
determinations of the IMF; 3) deriving disk frequencies throughout the cluster
and in sub-regions with different stellar densities and UV-radiation fields.

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.
