We propose to observe the open cluster NGC 6475 (age virgul220 Myr, Fe/H = 0.14 +-0.06) to investigate the activity-rotation-age relationship of low-mass stars inthe crucial age interval between the Pleiades and the Hyades. We will useXMM-Newton observations of the proposed cluster to go a factor of 10 deeper thanROSAT (to detect new faint candidate members) and to obtain spectral informationon the brightest cluster members (to derive coronal temperatures andmetallicities). These observations will provide strong constraints on theuniversality (or lack of) of the activity-rotation-age relationship, and henceon dynamo models of stellar coronal activity.

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.
