| Abstract | We propose an extensive investigation of the impact of stellar X-rays on theplanet-forming molecular environments of T Tauri stars by combining X-ray datafrom XMM-Newton with novel far-infrared spectroscopy from our Herschel OpenTime Key Project and complementary mid-infrared spectroscopy from Spitzer. Theprincipal goals are, i) to identify X-ray tracers in the Herschel spectralrange, ii) to study the potential impact of X-rays on circumstellar disks, andiii) to model physical and chemical conditions in the regions where the X-rayimpact is significant. We wish to understand how X-ray radiation influencesstar- and planet formation through physical and chemical processing of disks.Understanding the distribution of the astrobiologically important water plays a key role. |

| 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. |
