Abstract | An optical variability study of the benchmark star forming region NGC2264,observed with CoRoT, suggests that the cluster is more extended than currentlybelieved. To confirm this result we obtained, in AO10, a 50ks EPIC pointingtoward the cluster periphery. The observation fully confirms the existence of aspatially extended population. We propose to observe four more fields each for50ks. Our goals are: 1) establishing whether the clustered and dispersedpopulations originated from the same or distinct formation events; 2)determining whether mass segregation affects NGC2264, thus compromising currentdeterminations of the IMF; 3) deriving disk frequencies throughout the clusterand in sub-regions with different stellar densities and UV-radiation fields. |

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. |
