Description We propose continuation of our long-term monitoring program to identify and
study the cyclic behavior of the coronal emission of stars similar to our Sun,
that has been ongoing since XMM.s AO-1. Five stars in three stellar systems have
been monitored at regular cadence for almost two decades, providing for the
first time clear evidence of long-term cycles in the coronal activity of normal
stars. Thanks to the program.s continuity, this is a data set with unique legacy
value for the understanding of ..normal stellar coronae. Continuation of the
program into AO-19 is needed to progress in the understanding of the coronal
behavior across different activity cycles, and to link the extant time series of
XMM data with the photometric X-ray monitoring that will be performed by eROSITA.

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.
