| Abstract | We propose a pilot survey for X-ray emission from AGB stars that are candidatesfor having binary companions with active accretion. These objects wereidentified via our innovative technique to search for FUV/NUV excesses in AGBstars using GALEX. The detection (or non-detection) of X-rays from this samplewill enable us to begin testing models for the origin of the UV-excesses,leading to vital breakthroughs in our understanding of accretion-relatedphenomena and binarity in AGB stars. A larger survey, optimised using resultsfron this study, will be proposed in future cycles. |

| 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. |
