Small rotating clouds of stellar mass in Orion molecular cloud 1
- 1. Department of Physics, University of California, Berkeley
Description
A region in the Orion molecular cloud containing NH3 and 3''.5 north of BN/KL has been examined with the high angular and spectral resolution of the VLA. Observations of the NH3(1,1) and (2,2) inverison transitions reveal at least two small cloud fragments about 0.05 pc across that rotate rather rapidly and have masses approximating that of normal stars. Optical depth of the (1,1) transition is tau = 7 and the temperature is about 20 K. These clumps are likely candidates for a stage of cloud development shortly before the formation of low-mass protostars
