Description The axisymmetric structures of most planetary nebulae (PNe) have led many people to suggest that stellar magnetic fields shape the winds from asymptotic giant branch (AGB) star progenitors of PNe. We seek here to determine the X-ray emission properties of AGB stars and, thereby, to understand and set constraints on magnetic (dynamo) activity in AGB stars. The results will inform new theories on the shaping of the winds from AGB stars and, hence, the shaping of PNe, and furthermore have the potential to establish the presence of stellar dynamos and magnetic activity in a new class of object. Only XMM, with its unsurpassed sensitivity and good spectral resolution, can be used to carry out this investigation.

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.
