Scientific paper

We propose to carry out a complete X-ray census of planet-bearing host stars with a distance limit of 30 pc. We specifically propose to obtain well-exposed EPIC spectra of those stars harboring close-in (Porb < 10 days) planets and to carry out detection experiments on planet-bearing stars hitherto not detected in X-rays. With the these data we will characterize the high-energy radiation field for a representative sample of nearby planet-bearing stars, compute the expected evaporation rates due to the host stars' X-ray and UV irradiation, study the metal abundance of the coronae of planet bearing host stars, assess the frequency of flaring events in our sample, construct luminosity distribution functions and place the high-energy environment of the Sun in the context of that for extrasolar planets.
