The ROSAT spectrum of the symbiotic nova AG Pegasi: evidence for colliding winds.
MUERSET U., JORDAN S. and WALDER R.
Abstract (from CDS):
Pointed ROSAT PSPC observations of the symbiotic nova AG Peg are presented and analyzed. A basic analysis shows that the X-rays are emitted by a hot - probably shock-heated - plasma with a temperature of a few MK. We suggest that we are facing the first definite observation of colliding winds in a symbiotic binary system. Using a one point model, we derive for the emitting plasma a characteristic temperature of 3.5x106K, a luminosity of 0.01L☉bol, and an emission measure of 1.5x1054cm–3. A 2D hydrodynamic simulation resting on published system parameters reproduces these results.
