JWST will launch during HST cycle 28 and begin a new era in atmosphericcharacterization for all types of exoplanets. Atmospheric spectroscopy of warmrocky planets, sub-Neptune, and Jupiter-mass planets will be obtained through arobust set of guaranteed transiting planet observations (the JWST ERS and GTOprograms). We propose to obtain temporally-resolved UV (1150-3200 Ang) stellarspectroscopy of the 13 JWST guaranteed time targets with no UV characterizationdata in the HST archive. Our proposed observations will provide the UV contextnecessary to determine the likelihood of atmospheric formation and retention,the identification and interpretation of atmospheric chemistry, and the impactsof stellar activity on the exoplanet atmospheric stability.

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.
