The Gaia-ESO Survey will provide the first homogeneous spectroscopic study ofthe kinematics and elemental abundances of open clusters. Combined with X-raydata, it will allow a complete characterization of the cluster populations andof magnetic activity as a function of age, metallicity, ambient environment anddynamical evolution, improving our understanding of the activity-rotation-agerelationship. Here we propose to observe the four young open clusters IC 4665,NGC 2451, NGC 6504 and NGC 6716, to complete the sample of nearby clusters inthe Survey observed with modern X-ray telescopes, and to fill the gaps in thecrucial 30-100 Myr age range where the transition from pre-main sequence to mainsequence X-ray activity regime occurs.

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.
