| Description | We propose to obtain snapshot observations of a sample of ultra-active planet hosts. The sample is complete in that it comprises all known transiting systems (not observed/proposed) within 250 pc, orbital periods below 10 days and strong activity as photometric variations in excess of 1% and/or Ca II emission; the sample does include all suitable objects detected by Kepler. The sensitivity of the proposed XMM-Newton observations allows the detection of stars with X-ray luminosities in excess of 10^29 erg/sec. Because of the proximity to their hosts these planets are the prime candidates for the process of planetary atmospheric evaporation through hydrodynamic blow-off. With our study we establish the hosts. high-energy properties and pave the way for meaningful follow-up studies. |

| 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. |
