| Abstract | Symbiotic binaries---compact objects (typically white dwarfs) accreting fromcool giants--- are laboratories for accretion physics and the progenitors ofsome supernovae. The giant outshines many optical signatures of accretion, soalmost all known symbiotics have been found through emission line surveys.Symbiotics identified in this way often contain luminous WDs with shell burningon their surfaces. But now, using the SkyMapper survey, we are using uvg colorsand variability to find both burning and non-burning symbiotics. Here we requestsensitive X-ray exposures and UV light curves of our best candidates, which onlyXMM can provide. Detecting X-ray emission with EPIC or UV flickering with the OMwill validate our method and reveal a hidden population of non-burning symbiotics. |

| 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. |
