Shaping proto-Planetary Nebulae by binary systems
Abstract
We present the results of 3D hydrodynamic simulations aimed to explore the binary scenario for shaping bipolar, point- and
mirror-symmetric proto-Planetary Nebulae. We consider a jet launched by the secondary star of a binary system, located at the center of the PPN, which propagates within a circumstellar medium swept previously
up by the wind of the giant companion. As a result of the presence of the companion star, the accretion disk around the jet source is likely to precess. We apply the combination of an orbital motion plus a precession to the well-known proto-PNe Red Rectangle and
CRL 618.
