| Description | We propose to observe 16 nearby late-type giants in order to perform a study of a complete volume-limited sample of single late-type giants within 35 pc. Deep EPIC pn observations will yield detections and X-ray fluxes at solar activity level, which is the minimum yet observed in such stars. Substancial constraints are expected towards our understanding of issues like the evolution of stellar activity in post main-sequence phases, the mechanisms of dynamo action in giant stars, and the scatter of activity in stars of similar properties and evolutionary stage. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
