H2 2.12 μm Spectroscopy and Imaging of HH Objects
Abstract
We have obtained high spectral resolution observations of a number of Herbig-Haro (HH) objects in the H2 v=1=0 S(1) line at 2.12 μm. Objects observed included HH1/2, HH7-11, HH19, HH32A, HH40, and HH43, all associated with jet-like features or collimated optical outflows. Here we present velocity-resolved 2.12 μm spectroscopy for HH40 (an HH-object moving close to the line of sight) and for HH43B (an HH-object moving close to the plane of the sky). The full set of observations including interpretation is given in Zinnecker et al. (1989). We also present high spatial resolution H2 2.12 μm images of HH40 and HH43.
