X-ray Spectra of Pleiades Coronae

GTXray 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 EPICXMM for its Xray 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. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
