| Abstract | TESS is soon to boost the number of known exoplanetary systems especially withEarth-size planets around nearby, small (M-type) stars. Irradiation by thestars. high-energy emission can severely affect the planet atmospheres which,therefore, cannot be characterized without knowing the host star X-ray/UV (XUV)properties. These emissions are also key diagnostics of stellar dynamos and atracer of spin evolution in fully convective stars. Yet, >40% of the M dwarfswithin only 10pc have no tight limit on their X-ray emission. We, thus, proposean XUV XMM-Newton survey of all 41 still X-ray undetected early- to mid-M dwarfswithin 10pc, providing the ultimate constraint on M dwarf XUV emission as vitalinput to models of planetary atmospheres, dynamos and spin evolution. |

| 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. |
