Turbulent accretion disks are the most probable origin of jets from young stellar objects. Using an extended version of ZEUS-3D code in the axisymmetry option we investigate the evolution of a disk wind into a collimated jet. Resistive jets propagate slower with increasing magnetic diffusivity, and the degree of collimation decreases. The resistive disk included in the simulations ejects persistent, well collimated jet.

Collimation of astrophysical jets : The role of the accretion disk magnetic field distribution
We investigate the influence of the accretion disk magnetic flux profile on the collimation of jets applying axisymmetric MHD simulations. We use the ZEUS-3D code modified for magnetic diffusivity.
