Scientific paper

In an attempt to identify the molecular shocks associated with the entrainment of ambient gas by collimated stellar winds from young stars, we have imaged a number of known molecular outflows in H2 v=1-0 S(1) and wide-band K. In each flow, the observed H2 features are closely associated with peaks in the CO outflow maps. We therefore suggest that the H2 results from shocks associated with the acceleration or entrainment of ambient, molecular gas. This molecular material may be accelerated either in a bow shock at the head of the flow, or along the length of the flow through a turbulent mixing layer.
