Scientific paper

Images of the outflow complexes HH 1-2, HH 19, HH 33-40, and M 78, seen in the light of the 2.12-micron line of molecular hydrogen, are presented. The brightest molecular hydrogen emission is associated with the working surfaces of the outflows. The H2 emission appears clumped on a similar scale to the S II 6717-31-AA forbidden line emissions, which are normally associated with low-excitation shocks. H2 emission is also observed from the jet which apparently drives HH 33. Infrared continuum observations of the M 78 complex are discussed in terms of a massive disk associated with the outflow driving source SSV 63.
