Scientific paper

In the present maps of the molecular cloud associated with the multiple IR source GL 437, C-12O and C-13O data indicate that cloud density varies as r to the -3rd, where r is the distance from the IR cluster. The C-13O spectra show no evidence for the shifts in the center line velocity which would be expected if there were a significant rotational component for the cloud's velocity field. Detailed mapping of the C-12O around the IR cluster shows that there is significant line broadening within about 2 pc of the IR emission peak. These data also reveal a second peak 4 pc north, which has half the intensity of the emission centered on the previously studied IR source and may be associated with a previously unobserved IR source.
