| Description | The high-energy radiative environment around low-mass stars is driven by emissions from the stellar upper atmosphere, including the transition region and corona. These emissions from X-rays to ultraviolet wavelengths have important consequences for exoplanetary atmospheres and their evolution, including significant mass loss and atmospheric chemistry. We propose to measure the X-ray emission in a UV selected sample of active M-dwarfs to examine the rotational evolution of both X-rays and UV emission, and constrain how M-dwarf coronal structure changes with angular momentum evolution. These data will enable new efforts to estimate otherwise unobservable extreme ultraviolet emission, an important ingredient in planet atmospheric modeling, through modeling of the coronal atmosphere. |

| 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. |
