Abstract
In the usual theoretical picture of star formation a jet is ejected from a magnetized accretion disk, with a molecular outflow being driven either by the jet or by a wider wind coming from the disk. We propose an alternative unified model for the flows surrounding YSOs. In addition to a central accretion-ejection engine driving the jet, the molecular outflow is powered by the infalling matter and follows a circulation pattern around the central object without being entrained by an outflow. Jets solutions from this model have been used as initial conditions for simulations of the propagation of pulsed jets. Synthetic maps from the jet simulations are presented.
