Ja. Tedds et al., OBSERVATIONS OF SHOCKED [FEII] AND H-2 LINE-PROFILES IN ORION BULLET WAKES, Astrophysics and space science, 224(1-2), 1995, pp. 139-142
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.
