Launching and propagation of protostellar jets

We present resistive MHD simulations of jet launching and propagation using the PLUTO code. The main question we address is which kind of disks launch jets and which kind of disks do not? We investigate the jet-disk interaction applying different profiles of the disk magnetic diffusivity and derive the corresponding accretion and ejection rates for bipolar outflows. We determine the launching disk area of the fast component of protostellar jets. We further investigate numerically symmetry aspects of jet and counter jet. Finally, we present a model explaining the observationally indicated jet rotation by MHD shocks of the helical magnetic field in the propagating jet.
