Abstract

Long filamentary structures composed of chains of denser clumps fan out from the high mass star-forming KL core region in OMC-1. We present a high resolution VLA NH3 study of the structure, kinematics, and temperature of the region over a large, multi-field scale. The region appears to contain multiple superimposed cloud components. Clumps along the filaments may be the result of instabilities and fragmentation; some show fast velocity gradients. Sheaths around the clumps along the filaments are heated. This is possibly the result of external radiation or of interaction with high velocity outflows from young stellar objects in OMC-1.
