| Description | Accretion disks in symbiotic stars are often hidden by the bright optical emission from the red-giant companion, UV emission from the ionized nebula, and soft (E < 2 keV) X-rays from colliding winds. A survey with Swift, however, has revealed that the accretion disks dominates above 2 keV, as well as in the rapidly variable portion of the UV light. Our proposed simultaneous X-ray and UV observations of 3 targets from the Swift survey with XMM-Newton is uniquely suited to pioneer the study of these important disks and determine the range of accretion rates in symbiotics; compare the properties of the flickering with other disk accretors; and confirm the primary results of the Swift survey. This research has implications for the physics of accretion disks and symbiotics as SNIa progenitors. |

| 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. |
