Description Hot Jupiters are gas giant extrasolar planets close to their host stars. In two stellar systems with hot Jupiters, a cyclic variation of chromospheric activity synchronized to the planet.s revolution, and not to the stellar rotation, was observed. The proposed mechanism to explain this activity enhancement is a magnetic interaction between the star and the hot Jupiter. The extrasolar planet WASP-43b with a period of 0.81d is the closest-orbiting hot Jupiter. WASP-43 also shows a 15.6d rotation period, and the presence of strong Ca H+K emission indicating that it is an active star. We propose a short observation of WASP-43 to determine its X-ray flux in order to prepare a future longer X-ray observation of this remarkable system.

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.
