The Impact of Outflows: From Low to High Mass Protostars
Résumé
Despite the importance of outflows in removing angular momentum and mass from protostellar envelopes, we struggle to understand their origin, their changes with mass and evolutionary stage of the protostars, and their impact on the dynamics of proto-clusters. Here we present our recent observational work addressing these issues, including the study of a low mass star forming region (B59), with a direct measurement of the outflows impact and turbulence injection; and a test of low mass evolutionary models on a sample of high mass protostars in Cygnus X.
