Launching of resistive magnetic protostellar jets

Abstract

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.
