|Title||Star-Planet Magnetic Interaction in Extra-Solar Systems with Hot Jupiters|
|Author||Dr Antonio Maggio|
|Description||The significant fraction of Jupiter-size exoplanets orbiting at a few stellar radii from the parent stars (hot Jupiters) rises the question whether effects of magnetic star-planet interactions (SPI) can be detected. We focus our attention on systems with very eccentric orbits, where we expect to detect systematic effects, like enhanced stellar activity, when the planet is at the closest separation. We propose to take snapshots of the systems HD17156 and HD 162020 with XMM-Newton, when the hot Jupiter is at the periastron and off periastron, in order to detect SPI effects in X-rays. Comparison with model predictions will allow us to infer the energy budget involved in SPI and the strength of the magnetic field of the planet.|

|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.
