| 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. |
