Hydrodynamics, Shocks, Ism: Jets And Outflows

Scientific paper

We describe an effective mechanism for collimating the outflow from a young stellar object (YSO). Our study is based on a series of numerical simulations of the interaction of a central, isotropic wind with a toroidal circumstellar accretion flow. A bipolar shock configuration is quickly established as a consequence of the decrease of the accretion flow density from equator to pole. The jet is collimated through the inertial confinement mechanism (Icke et al. 1992). A prolate inner shock focuses the wind toward the axis forming the jet. At the same time the contact discontinuity at the equator becomes unstable and is dragged by the jet into a chimney. This chimney confines the high-velocity gas and maintains the collimation. The kinematical pattern of the outflow is consistent with the observations.
