Scientific paper

Symbiotic binary stars have until now been thought to produce predominantly soft X-rays. With the advent of INTEGRAL and Swift, however, at least three symbiotics have been found with emission out to greater than 50 keV. The origin of such hard X-ray emission from these presumably accreting, non-magnetic white dwarfs (WDs) is a mystery. Possible explanations include: 1) boundary-layer emission from accretion onto a near-Chandrasekhar-mass WD; 2) non-thermal emission from a jet; and 3) emission from an accretion column on a WD not previously recognized as magnetic.We propose to begin an investigation of hard X-ray symbiotics with RT Cru, which is currently in an optical bright state.
