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.
