Abstract
Recent near-IR imaging of the Orion molecular cloud has revealed a com plex of dense bullets, Visible as [Fell] emitting HR-objects at the ti ps of H-2 wakes, ejected explosively from the cloud core. Having resol ved individual bow-shock structures for the first time in this bright source, we have observed [FeII] 1.644 mu m velocity profiles of select ed bullets and H-2 1-0 S(1), 2.122 mu m velocity profiles for a series of positions along and across the corresponding bow-shock wakes. We p resent observed profiles for the bullet M42 HH1 and its associated wak e and compare with theoretical bow-shock models.
