The significant fraction of Jupiter-size exoplanets orbiting at a few stellarradii from the parent stars (hot Jupiters) rises the question whether effects ofmagnetic star-planet interactions (SPI) can be detected. We focus our attentionon systems with eccentric orbits, where we expect to detect systematic effects,like enhanced stellar activity, when the planet is at the closest separation. Wepropose a follow up campaign in X-rays of the system HD 162020 to confirm aprevious SPI effect suggested by observations with Suzaku. Comparison with modelpredictions will allow us to infer the energy budget involved in SPI and thestrength of the magnetic field of the planet.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
