| Abstract | We propose to carry out a complete X-ray census of planet-bearing host starswith a distance limit of 30 pc. We specifically propose to obtain well-exposedEPIC spectra of those stars harboring close-in (Porb < 10 days) planets and tocarry out detection experiments on planet-bearing stars hitherto not detected inX-rays. With the these data we will characterize the high-energy radiation fieldfor a representative sample of nearby planet-bearing stars, compute the expectedevaporation rates due to the host stars X-ray and UV irradiation, study themetal abundance of the coronae of planet bearing host stars, assess thefrequency of flaring events in our sample, construct luminosity distributionfunctions and place the high-energy environment of the Sun in the context of that for extrasolar planets. |

| 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. |
