We intend to measure the radiation in the X-ray band (especially the emission atenergies higher than 1 keV) of four stars known to host giant planets. The X-rayspectra will be used as input in our models to study the effects of high-energyradiation on planet atmospheres. The selected stars have X-ray luminositysimilar to that of young solar analogs, and will serve as a first step to testthe influence of the high-energy radiation on the early planetary atmospheresanalogous to the young stages of the Solar system, and its subsequent evolution.

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.
