Description HST observations show that three of the brightest transiting exoplanets are evaporating (HD209458b, HD189733b and GJ436b) and models suggest that the evolution of close-in low-mass planets may be dominated by this mass loss. Simultaneous X-ray and ultraviolet observations of planetary transits are needed to constrain self-consistent models of the exoplanetary winds. Here we propose transit observations of four bright exoplanets with XMM in order to determine mass loss rates.

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.
