| Abstract | The recent discovery of Pi Men c, a super-Earth transiting an outstandinglybright nearby star (V = 5.67; 18 pc), presents an unrivalled opportunity tostudy the atmosphere of a small planet just above the radius-period valley..While the expected transit signature of the atmosphere in the optical/infraredis very small, the high-energy environment of the planet is thought to befavourable for large transit absorption features in the far- ultraviolet due toan escaping, extended upper atmosphere. Using simultaneous XMM-Newton and HSTobservations, we propose to perform both a full reconstruction of thedifferential emission measure in order to characterise the high-energyirradiation impingent on the planet, and a sensitive search for evaporation signals due to these photons.

| 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. |
