Description The rotation-activity relation of M dwarfs is of high astrophysical interest due
to (i) the predicted dynamo transition at the fully convective boundary (SpT virgul
M3), (ii) differences in angular momentum loss with respect to solar-type stars,
and (iii) the small radii of their planets. habitable zones where they are
strongly exposed to the stellar high-energy emission. Our combined K2 mission
and Chandra study has shown that previous studies of the X-ray - rotation
connection are incomplete for slowly rotating and low-activity fully convective
stars. We aim here at placing the ultimate constraints with ultra-deep
XMM-Newton pointings for three bright, nearby fully convective (M4) stars that
have long rotation periods (30.80 d) derived by us from K2 lightcurves.

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.
