|Title||Two X-ray luminous symbiotics in the SMC|
|Author||Dr Marina Orio|
|Description||We have been studying for years two symbiotic binaries in the Small Magellanic Cloud that host nuclear burning white dwarfs. They belong to a group of observed symbiotics that may represent only the "tip of the iceberg" of a large class of such binaries hosting massive white dwarfs with shell nuclear burning. They constitute primary candidate for type Ia supernovae from single degenerate systems, or may instead evolve to "double degenerates". The supersoft X-rays are the only window to observing nuclear burning directly, and long term monitoring is necessary to assess the parameters to evaluate the evolution of these binaries.|

|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.
