ABSTRACT
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.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
