| Abstract | HST observations show that three of the brightest transiting exoplanets areevaporating (HD209458b, HD189733b and GJ436b) and models suggest that theevolution of close-in low-mass planets may be dominated by this mass loss.Simultaneous X-ray and ultraviolet observations of planetary transits are neededto constrain self-consistent models of the exoplanetary winds. Here we proposetransit observations of four bright exoplanets with XMM in order to determinemass loss rates. |

| 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. |
