Abstract
We perform a numerical study of the formation and stability of a Blandford-Rees (BR) twin exhaust jet. A de Laval nozzle is indeed created and stably maintained over a central luminosity range of ~40. However, the cavity-nozzle structure is compact and dominated by a central spherical shock unlike BR’s original models. We find a new global Rayleigh-Taylor instability which limits the formation of high-luminosity jets. A useful formula is discovered for relating the jet luminosity to the internal energy of the confining cloud.
