Abstract We will use XMM in concert with JWST/MIRI to characterize the impact of XUVradiation on the chemical composition of the hot H/He-rich atmosphere of HD106315c, orbiting a bright F5V star in a 21.06-day orbit. MIRI will probe, viaSO2, the planetary atmosphere???s sulfur reservoir, to verify the impact of XUVradiation on the upper-atmosphere chemical composition. Also, XMM will quantifythe X-ray and UV broad-band fluxes impinging on the atmosphere that are r^antfor atmospheric heating and loss. These observations are crucial to understandthe different effects of planet formation, atmospheric loss and photochemistryon the upper-atmosphere chemical composition of this Super-Neptune-mass planet,and augment a small but important dataset of exoplanets having both JWST and XUV data.

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.
