Abstract | 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. |
