Abstract We propose to observe 16 nearby late-type giants in order to perform a study ofa complete volume-limited sample of single late-type giants within 35 pc. DeepEPIC pn observations will yield detections and X-ray fluxes at solar activitylevel, which is the minimum yet observed in such stars. Substancial constraintsare expected towards our understanding of issues like the evolution of stellaractivity in post main-sequence phases, the mechanisms of dynamo action in giantstars, and the scatter of activity in stars of similar properties andevolutionary stage.

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.
