We have collected initial evidence that tidal interaction between a late-typestar and its close-in, massive planet can lead to a spin-up of the host star. Wepropose to explore this further by studying a small sample of proper motionpairs in which one of the stars is orbited by a Hot Jupiter. We will determineif the activity-estimated age appears to be strongly different for the twostars, which would indicate a tidal spin up of the Hot Jupiter host star. Wepropose to observe 4 such systems with Chandra/ACIS-S, and to perform a similarobservation of one additional system with large angular separation usingXMM-Newton/EPIC. Thetotal proposed exposure times are 141 ks (Chandra) and 38 ks (XMM).

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.
