|Title||Gas, Dust, and X-Rays in the Disks around T Tauri Stars|
|Author||Dr Manuel Guedel|
|Description||We have initiated a project to diagnose the intertwined processes of gas heating, dust settling and chemical processing in a set of well-characterized disks around T Tauri stars. We have developed detailed models describing gas and dust evolution in accreting disks irradiated by X-ray and UV photons. These models are tested by molecular diagnostics obtained with (sub-)millimeter interferometers. However, detailed X-ray spectra are not yet available for many of these objects. Here, we request observing time to obtain X-ray spectra from several disk-harboring T Tau stars at various inclinations, which will allow to measure gas-to-dust ratios and provide important input to our chemical and turbulent models of circumstellar disks.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
