Abstract
We have mapped the high-velocity emission in the wings of the CO line at the Kleinmann-Low infrared nebula. The half-power diameter is found to be 80 arcseconds. Upon analysis of the observed intensity profiles and the variations in angular size at different velocities, we conclude that a differentially expanding envelope, possibly the result of an explosive event, is the most likely explanation. The kinetic energy in the flow is 4 x 10^(47) ergs, based on a numerical model of the CO emission. The recently observed v = 1 → 0 radiation of H_2 would arise from the shock front preceding the expanding gas.
