Description I have proposed a new interpretation of the X-ray spectra of symbiotic stars: that they are dominated by absorption by the partially-ionised wind of the red giant, and not by emission from colliding winds as was previously thought. My interpretation predicts that all systems with apparent colliding-wind ROSAT spectra should also have hard X-ray emission. I propose XMM-Newton observations of three bright symbiotic stars aimed at detecting this emission. Once the colliding-wind model has been disproved these observations will also be used to model the partially-ionised absorption which will provide a powerful probe of the red giant wind and of wind accretion onto a compact object.

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.
