Abstract	Stellar X-ray irradiation drives planetary winds, whose properties remainlargely unknown. WASP-69 b could be the most heavily evaporating hot Neptunewithin 100 pc, driving a wind 50 times stronger than that of HD 189733 b. Thismakes the system a highly promising new target for transit studies. The X-rayproperties of the host star remain puzzling, however. Scaling the Ca H&Kemission suggests an X-ray luminosity of 1-6e28 erg/s -- consistent with itsprevious identification with a ROSAT source at 60 distance. However, in afollow-up SWIFT snapshot, neither X-ray emission from WASP-69 nor the ROSATsource were detected. We propose a dedicated XMM observation to quantify theX-ray properties of WASP-69 and study the strong planetary wind.

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.
