Description We propose to continue the ongoing long-term monitoring program of a sample of solar-type stars to search for cyclic behavior, analogous to the one observed for the Sun, in their X-ray emission. These stars have moderate levels of activity and are thus true ..solar analogs.. XMM-Newton makes it possible, for the first time, to efficiently monitor the low-activity, cyclic stars and to effectively study the characteristics of the activity cycles on stars other than the Sun.

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.
