|Title||X-ray emission in the Eta Chamaleontis cluster|
|Author||Dr Javier Lopez-Santiago|
|Description||The Eta Chamaleontis cluster (6-8 Myr, d virgul 97 pc) is one of the most important nearby T associations. Its members are in an evolutionary stage in which warm inner discs, and consequently most of the accretion phenomena, are lost. These are also the time scales of planetary formation and migration. We propose to make observations pointed at the centre of the Eta Chamaleontis cluster using the EPIC cameras. We will analyse the X-ray emission of the detected sources. Our aim is to establish a complete census of X-ray emitters members of the cluster and characterize their corona in terms of temperature, emission measure, and X-ray luminosity. The results will be compared with those of other young T associations, both isolated and in star-forming regions.|

|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.
