Description A program to detect and study for the first time solar-like cyclic behavior in the X-ray emission of stars similar to our Sun has been ongoing since XMM s AO-1. Five targets in three stellar systems have been monitored since 2000, providing for the first time evidence of long-term cyclic behavior in the X-ray luminosity of normal stars, with variations in X-ray luminosity of up to an order of magnitude. The present proposal requests continuation of the ongoing monitoring program into XMM AO-6, needed to progress toward the complete observation of at least one stellar activity cycle for our targets.

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.
