Title X-Rays from Micro-Jets of Classical T Tauri Stars


DOI 10.5270/esa-798jcll
Author Dr Manuel Guedel
Description Recent observations of some classical T Tau stars have revealed an anomalous type of thermal X-ray spectrum characterized by the superposition of a steady, very soft and little absorbed component and a very hard, strongly absorbed and flaring component. While the latter is probably originating in a magnetic corona, the former has been interpreted as being X-ray emission from the shocked base of the jets detected in these sources. We propose a systematic, small survey of nearby jet-driving classical T Tau stars to determine if such unusual spectra are a general property of these objects and to elucidate the underlying heating process.

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.
