Abstract

We present new, high-resolution, near-infrared images of the HH 1 jet and bow shock. H2 and [Fe II] images are combined to trace excitation changes along the jet and across the many shock features in this flow. Echelle spectra of H2 profiles towards a few locations in HH 1 are also discussed. Gas excitation in oblique, planar C-type shocks best explains the observations, although J-type shocks must be responsible for the observed [Fe II] emission features. Clearly, no single shock model can account for all of the observations. This will probably be true of most, if not all, Herbig-Haro flows.
