Abstract	Accretion disks in symbiotic stars are often hidden by the optical emission fromthe red-giant companion, UV from the ionized nebula, and soft X-rays fromcolliding winds. A survey of symbiotic with Swift, however, has revealed thatthe accretion disk dominates above 2 keV and in the rapidly variable portion ofthe UV. To determine the basic properties of the large, wind- fed accretiondisks around the white dwarfs in symbiotic, we propose X-ray and UV observationswith XMM-Newton of the two most promising targets from our Swift survey. OnlyXMM can provide the sensitive, contiguous, multi-wavelength observations todetermine the accretion rates, characterize the properties of the UV flickeringand test our conclusion that hard X-rays originate in the innermost accretion disk.

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.
