Abstract We propose continuation into AO13 of the ongoing long-term program for themonitoring of coronal cycles in a sample of five solar-type stars in threestellar systems. The targets have been monitored continuously since AO1,yielding the first unambiguous evidence of cyclic behavior in the X-ray emissionfrom the coronae of cool stars. Thanks to the long-term monitoring our programis starting to show evidence of the complex behavior of stellar cycles, withsignificant cycle-to-cycle variability becoming apparent. The observationsrequested in AO-13 will allow us to capitalize on our long-term investment ofXMM-Newton observing time and to continue assembling a unique long-term data setthat is likely to remain unmatched for a long time.

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.
