The jet and energy source of HH 46/47.
Abstract
The HH 46.47 Herbig-Haro complex has been studied during both high spatial resolution narrow band CCD images and long-slit spectroscopy. Deep interference filter CCD images show that the jet consists of numerous resolved knots which are bright and sharply defined in the forbidden S II but fainter and more diffuse in H-alpha. The jet appears to be divided into two clearly separated parallel strands and is not perfectly straight. The jet section closest to the source is extended in a direction very different from the axis of the rest of the jet, which itself has several changes of direction. A well-collimated counterjet emanates from a point close to the source. There is a marked asymmetry between the approaching and the receding lobes of the flow. It is argued that HH47D, HH47A, HH47C, and possibly HH47B are each independent working surfaces embedded in the flow, and the HH46/47 complex is interpreted in terms of multiple ejections from the embedded energy source.
