New Models for Star Formation and Consequences on the Interstellar Medium

  • Thibaut Lery

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. We present a possible temporal sequence for the flows around a protostar and their effects on the surrounding medium.

Keywords
