|Title||Evolution of coronal activity from observations of open clusters and SFRs|
|Author||Prof Roberto Pallavicini|
|Description||GT-Open clusters and young stellar associations offer unique opportunities to study the evolution of angular momentum in late-type stars and the dependemce of coronal activity upon age, rotation and mass. We propose to carry out a spectroscopic survey of several nearby open clusters of different ages and of a few star forming regions (SFRs) with the aim of deriving the evolution of coronal properties for stars of different masses. The selected clusters (IC2602, alpha Persei, Hyades and Praesepe) span the age range from 30 Myr to 700 Myr, while the lelected star forming regions (NGC2024 in Orion and Taurus-Auriga) will allow us to further extend this study to ages as young as 1 to 10 Myr. Other clusters and SFRs will be observed by other XMM GT and GO programmes.|

|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.
