Abstract | Observations of old open clusters have been performedwith ROSAT but with limited sensitivity and spatial resolutionand allowed to investigate the evolution only of very active binaries. Currently the coronal activity-age relation beyond 1-Gyr is not known. We propose a 50 ks XMM-Newton pointingsto the 2-Gyr old clusters NGC 752 and IC 4651, which are well studied in the optical. We will study the coronal activity evolution in solar type stars, in post main-sequence and binary stars |

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. |
