| Abstract: |
LWS observations towards molecular outflows driving sources show that their FIR spectrum is often dominated by the emission of CO rotational lines. Model fits to these lines show that they originate from a dense and compact gas component with temperatures ranging from few hundred up to 1600 K. An analysis of their emission suggests that non-dissociative shocks are the main excitation mechanism, although in few cases other contributions may also be present. We discuss the origin of this shocked emission and how it relates to the large scale properties of the molecular outflows. |
