Scientific paper

We present Caltech Submillimeter Observatory 10" resolution maps of the 3P2-->3P1 line of neutral atomic carbon (809.3435 GHz) and the J=7-6 line of CO (806.6518 GHz) covering a region of 2'×4.5 arcmin around Orion IRc2 in the BN/KL Nebula. The two lines were observed with the same receiver simultaneously, and therefore the two maps have zero relative pointing error. The atomic carbon (C I) emission does not peak toward the IRc2 position and displays a very different spatial distribution with respect to most molecular species. Moderately strong red wings are detected in C I around the region defined by the high-velocity CO gas with a spatial distribution that delineates a shell of ~20" radius. We propose that CO dissociation in the J-type shocks produced by the interaction of the IRc2 outflows with the surrounding quiescent gas could play a significant role in this enhancement of atomic carbon in that shell.
