Description Although the Asymptotic Giant Branch (AGB) stars are well studied in some aspects, there are several properties that remain unexplored. For instance, the role of magnetic fields for the large-scale structure and dynamics of the circumstellar envelope (CSE) has not been established. Recent results from maser polarimetry observations indicate strong magnetic fields throughout the inner CSE. These need to be confirmed by the detection of X-ray emission from coronal activity. We propose to observe three low- mass-loss rate, close (<300 pc), AGB stars, in order to detect and establish the origin of X-ray emission. The observations would be a follow-up to our recent archival search that resulted in new X-ray detections of two AGB stars.

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.
