3 dimensional magneto hydrodynamic jet simulations.

Author list: Jan Staff

We present the results of four 3 dimensional magneto hydrodynamic jet simulations, with different initial magnetic field configurations. The simulations focus on the innermost regions of the jet.  While a Keplerian disk is put on the boundary, we resolve the inner edge of the disk in the simulations, and follow the jet out to 3000 times the inner edge of the disk. We show that depending on the initial magnetic field configuration, a two component jet structure consisting of a thin axial jet surrounded by a cylindrical shaped outer jet may form. In other cases, only the thin axial jet forms.
