| Abstract | We have been studying for years two symbiotic binaries in the Small MagellanicCloud that host nuclear burning white dwarfs. They belong to a group of observedsymbiotics that may represent only the tip of the iceberg of a large class ofsuch binaries hosting massive white dwarfs with shell nuclear burning. Theyconstitute primary candidate for type Ia supernovae from single degeneratesystems, or may instead evolve to double degenerates. The supersoft X-rays arethe only window to observing nuclear burning directly, and long term monitoringis necessary to assess the parameters to evaluate the evolution of thesebinaries. |

| 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. |
