|Title||The X-ray irradiation and evaporation of close-in extra-solar planets|
|Author||Dr Peter Wheatley|
|Description||The discovery with HST of the evaporation of the transiting exoplanet HD209458b has raised the possibility that the evolution of close-in planets is dominated by mass loss. This evaporation must be driven by the X-ray emission of the parent star, which we can measure directly with XMM-Newton. In this proposal we aim to measure the X-ray irradiation rate of two nearby transiting planets. This is an essential step in determining the role of evaporation in the evolution of close-in planets.|

|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.
