Description We have detected bright X-ray emission from the rapidly-accreting jet-driving T Tauri star RY Tau. Chandra ACIS-S spectra reveal a wealth of emission lines arising in a multi-temperature plasma consisting of a superhot variable component and a very soft component traced down to approximately 0.2 keV. ACIS-S images show faint soft emission extending outward along the jet. We propose to obtain a high-resolution grating spectrum of RY Tau using RGS. The spectrum will provide crucial information needed to construct a detailed emission model and identify the origin of the very soft component, which likely arises at the base of the jet or an accretion shock.

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.
