| Description | In 2009 we used XMM-Newton to observe the .hot Jupiter" HD189733b during a secondary eclipse. Basing on that observation we have published two interesting results: 1) a distinct softening of the spectrum at mid eclipse and 2) a post eclipse flare coincident with model predictions of the appearance of a magnetic footpoint on the rising limb. That single observation cannot firm evidence of a causal relation with phase and Star-Planet Interaction. We propose to re-observe this system during secondary eclipses four times in order to establish the systematic nature of these features. We propose to observe also the high eccentricity system GJ 436 at periastron as pathfinder for SPI in hot neptune planets. |

| 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. |
