Title X-ray chracterization of M-type dwarfs hosting super-Earth planets

Description We propose X-ray observations of nearby M-type dwarfs hosting low-mass extra-solar planets, recently discovered in the framework of a radial velocity survey with HARPS-N@TNG. In particular, we propose a pilot observation of GJ 3998, never observed at X-ray wavelengths, which harbors two super-Earths at close distances from the central star, whose transits will be probed by Spitzer in the next months. For two more targets we require X-ray spectral and time variability analysis to characterize the dose of high-energy radiation received by the newly discovered planets, to be employed for follow-up studies of the planetary atmospheres. A crucial ingredient for such studies is the X-ray radiation flux, and more in general an assessment of the activity level of the host stars.

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.
