We are proposing to extend our long-standing program to determine and studycoronal cycles in a small number of solar-type stars into AO-18. In addition toallowing us to extend the only extant data set concerning the presence of X-raycycles in stars other than the Sun, the proposed observation will allow us tolink the XMM data set with the all sky survey observations of the same systemsthat will be performed by eROSITA following its launch now planned for 2019.

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.
