| Description | The X-ray emissions from exoplanet host stars are a key to understanding the formation and evolution of planetary atmospheres. We propose X-ray observations of 13 stars with known transiting planets which will be combined with UV observations and synthesised EUV spectra to provide the crucial input for detailed atmospheric modelling. The data will be included in a catalogue of 75 stars covering the full cool star spectral range, and will become an invaluable reference for future exoplanet studies. The addition of these 13 targets will provide a complete sample out to 110 pc. The construction of this catalogue, and the development of the associated models, will lay a foundation for studying exoplanet atmospheres via transit spectroscopy and the interpretation of atmospheric biomarkers. |

| 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. |
