| Abstract | We have detected bright X-ray emission from the rapidly-accreting jet-driving TTauri star RY Tau. Chandra ACIS-S spectra reveal a wealth of emission linesarising in a multi-temperature plasma consisting of a superhot variablecomponent and a very soft component traced down to approximately 0.2 keV. ACIS-Simages show faint soft emission extending outward along the jet. We propose toobtain a high-resolution grating spectrum of RY Tau using RGS. The spectrum willprovide crucial information needed to construct a detailed emission model andidentify the origin of the very soft component, which likely arises at the baseof the jet or an accretion shock. |

| 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. |
