| Abstract | The high-energy radiative environment around low-mass stars is driven byemissions from the stellar upper atmosphere, including the transition region andcorona. These emissions from X-rays to ultraviolet wavelengths have importantconsequences for exoplanetary atmospheres and their evolution, includingsignificant mass loss and atmospheric chemistry. We propose to measure the X-rayemission in a UV selected sample of active M-dwarfs to examine the rotationalevolution of both X-rays and UV emission, and constrain how M-dwarf coronalstructure changes with angular momentum evolution. These data will enable newefforts to estimate otherwise unobservable extreme ultraviolet emission, animportant ingredient in planet atmospheric modeling, through modeling of the coronal atmosphere. |

| 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. |
