Abstract R Aqr: a white dwarf and a Mira red giant is ejecting jets in optical, radio andx-rays. The 35 arc sec x-ray jets appear to be evolving towards thermalequilibrium, based on Chandra data over 3.3 y. Peaks are seen at about theenergies of C V, C VI, N VII & O VII: evolved material from the WD or from theMira, but if so, where.s the Si? Are photons, fast particles, or bulk motion --a shock -- exciting these jets? A hard, variable point source at the centralbinary is enigmatic -- Fe K alpha 6.4 keV (reflection? What excites it?) plusemission over several keV above and below 6.4 (lines, or even a dopplercontinuum?). EPIC can provide enough detected photons in a reasonable observingtime to illuminate these questions, and RGS can identify the lines.

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.
