|Title||Super-soft X-ray emission from symbiotic stars with Raman OVI scattering lines|
|Author||Dr Gerardo Juan Manuel Luna|
|Description||Optical Raman OVI scattering emission lines have only been found in symbiotic stars and can therefore unequivocally identify these accreting white dwarf-red giant binaries. Moreover, because Raman OVI features are produced by the scattering of the OVI 1035 line in the UV, they likely reveal when quasi-steady shell burning makes a symbiotic white dwarf (WD) very hot and luminous. We propose an XMM observation of the recently found Raman emitter LMC 1 to confirm its shell burning, which will manifest as super-soft X-ray emission or strong UV emission without rapid flickering. Supporting the link between shell burning and Raman O VI emission will enable our RAMSES II team to use a narrow-band Raman filter on Gemini-GMOS to find new symbiotics and probe the origin of their shell burning.|

|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.
