|Probing the XUV environments of small, nearby transiting planets
|Mr George King
|As both the software and hardware for detecting exoplanets has improved in recent years, the population of small exoplanets in the Solar neighbourhood known to transit their star has increased significantly. Models suggest that such planets may be the rocky remains of once much larger planets that were stripped of their outer envelope due to the intense level of high energy radiation impacting their atmosphere. We propose to study five nearby stars that are known to host one or more planets of Earth and super-Earth size, in order to characterise their high energy environment, and provide results to complement future atmospheric studies with instruments such as HST and JWST.

|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.
