Based on the exciting results of small pilot X-ray surveys, we propose anextended survey for X-ray and UV emission from AGB stars that are candidates forhaving binary companions with active accretion. These objects were identifiedvia our innovative technique to search for FUV/NUV excesses in AGB stars usingGALEX. This survey will result in the first catalog of co-eval X-ray and UVobservations of AGB stars, and characterization of this high-energy emission(e.g., X-ray temperature, luminosity, variability). The survey will enable thedevelopment of models for the origin of these newly-discovered high-energyphenomena in AGB stars, and lead to vital breakthroughs in our understanding ofaccretion-related phenomena and binarity in AGB stars.

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.
