Title X-ray properties of planet-bearing host stars


DOI 10.5270/esa-cacc5en
Author Prof Jurgen Schmitt
Description 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.

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.
