We propose to measure the X-ray emission of the exoplanet host Wasp-80, which isthe most promising candidate in the search for expanded hot Jupiter atmospheres.X-ray and EUV radiation is absorbed in planetary atmospheres and for close-inplanets this leads to copious amounts of heating, causing expansion andmass-loss. To constrain models of these atmospheres, measurements of the highenergy stellar emission in combination with transit spectroscopy are essential.Together with upcoming Chandra and HST observations the proposed program allowsus to characterize the emission of eight host stars and identify the mostpromising targets for follow-up campaigns. Due to its recent discovery the bestcandidate, Wasp-80, is not contained in the Chandra observations.

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.
