Hydrodynamical Processes in the Draco Molecular Cloud
Abstract
IRAS 100 micron images of the Draco cloud show several cloud components with cometary plumes of material extending 7-10 pc. The brightest plumes are very uniform in thickness but often terminate in large amorphous regions. The structure is consistent with low Reynolds number hydrodynamics and is suggestive of a molecular cloud shedding material in a plume as it falls onto the galactic plane from the halo region. A subsequent study of the 100 micron images from the entire IRAS survey has revealed a total of 14 additional cometlike objects with /b II/ greater then 15 deg.
