An area of about 1/sup 0/x5 x 2/sup 0/x0, centered on l = 45/sup 0/x5 and b = 0/sup 0/x0, was mapped in the /sup 12/CO line at intervals of one beamwidth. A total of 22 individual CO cloud complexes was identified; the brightest of these is associated with a massive H I cloud and the H II region complex G45.5+0.1. This object most likely represents a small OB star cluster in its early stages of development. All other H II regions in the area mapped are likewise associated with CO maxima. The… CONTINUE READING
