Scientific paper

We propose an extensive investigation of the impact of stellar X-rays on the planet-forming molecular environments of T Tauri stars by combining X-ray data from XMM-Newton with novel far-infrared spectroscopy from our Herschel "Open Time Key Project" and complementary mid-infrared spectroscopy from Spitzer. The principal goals are, i) to identify X-ray tracers in the Herschel spectral range, ii) to study the potential impact of X-rays on circumstellar disks, and iii) to model physical and chemical conditions in the regions where the X-ray impact is significant. We wish to understand how X-ray radiation influences star- and planet formation through physical and chemical processing of disks. Understanding the distribution of the astrobiologically important water plays a key role.
