Molecular Outflow As Entrained Molecular Gas

Friedrich Wyrowski, Karl Menten

 

Molecular outflow is a prominent phenomenon that happens in the formation of the stars. The outflows with a finite opening angle is usually interpreted using the wind-driven shell model. However, as we show, the wind-driven shell model is not physically consistent, and has problems in reproducing the observations.

In this contribution, we present a wind-driven turbulent entrainment model that explains the outflows as the entrained molecular gas of the envelope. This model is self-consistent, and can reproduce the observed morphology and kinematic structure of the outflows. Observational tests of our model will be discussed.
