|Description||Transiting exoplanet atmospheres are a major topic of research. They allow us to further study their atmospheres, with transmission spectroscopy sensitive to the atmospheric composition. Data interpretation and modeling requires detailed knowledge of the incoming stellar radiation, especially in the X-ray and UV ranges, which drives atmospheric inflation and evaporation, and alters the atmospheric makeup through photochemical processes. We intend to observe a sample of exoplanets that are part of an HST program in UV to IR wavelengths. We will acquire X-rays data to get a reliable coronal model that allows us to create synthetic XUV spectra. This information is vital for photochemical and atmospheric escape models, needed to interpret the atmospheric features to be observed with HST.|

|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.
