Description Stellar activity plays a key role in the evolution of planetary systems. Hot Jupiters around active stars are immersed in intense high-energy radiation fields and particle emission. In particular hydrodynamic blow-off of the outer planetary atmosphere should occur, which leads to larger X-ray radii of hot Jupiters and to deeper eclipse depths at X-ray wavelengths, which should be observable with XMM-Newton. The extrasolar planet system CoRoT-2 harbors the most active planet host-star known to date; its unique properties actually allow to perform sensitive X-ray observations of planetary transits and study such blow-off phenomena. We simultaneously study the X-ray and optical variability of CoRoT-2 by observing 15 transits distributed over almost eight stellar rotations.

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.
