GT-X-ray spectroscopy of open clusters makes possible to study the propertiesof coronae of stars of a given age and metallicity, reducing the number ofparameters affecting the emission properties. The Pleiades cluster is a uniquetarget for EPIC-XMM for its X-ray luminosity, age, distance and space density.Physical parameters, such as membership probabilities, rotation and lithiumabundance are known for many stars. The selected Pleiades core field will allowus to observe a large number of members for which we will collect enough countsto perform meaningful spectra on a sample of stars of various spectral typesand different rotation. Our observation will allow understanding the physicsof young stellar coronae and the coronal evolution during the star life.

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.
