Abstract In order to explore the effect of a new variable governing the magnetic activityof stars, viz., the presence of giant planets, we propose a set of snapshotobservations of a carefully selected sample of stars using XMM-Newton.s imagingdetectors for a total of 135 ksec. Our sample includes stars with extremelyclose-in Extrasolar Giant Planets (EGPs), with orbital radii less than 0.15 AU,as well as a control group of stars with EGPs at relatively farther distances(orbital radii greater than 2 AU). With these observations, we will be able tocharacterize and quantify the effect of close-in EGPs on stellar coronae.

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.
