|Title||Stirring a Corona with a Super Earth|

|Description||Recently, two extremely close-in planets were discovered around the K0V star CoRoT-7, at distances of 0.017 and 0.046 AU, with 5 and 8 Earth masses respectively. There is thus intense interest in this system. X-ray observations will be an extremely useful and sensitive tool to probe it, because the nearness of the planets to the host star implies significant structural changes to the corona due to the interactions of the stellar and planetary magnetospheres. We propose to observe this system 5 times at the joint conjunctions of the planets for a total of 50 ksec, and 4 further times when the outer planet is at quadrature, for 20 ksec. We expect to detect the signature of the interaction unambiguously and will model the system with numerical MHD simulations.|

|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.
