AN EMBEDDED-CLUSTER OF STARS AT THE ROSETTE GMC CO PEAK

K'-band imaging of the Rosette GMC CO emission peak reveals the presen ce of a hitherto undetected small cluster of stars, coincident with th e IRAS source 06314+0427. High signal-to-noise K-band spectra have bee n obtained for two of the cluster members. The brightest cluster membe r (dubbed BG/IRS1) shows Brgamma 2.166 mum in emission. The spectrum o f a second member, BG/IRS4, contains weak absorption bands of (CO)-C-1 2, indicating it is much cooler than BG/IRS1. The tails of an optical family of cometary globules in the Rosette SE quadrant all point radia lly away from the newly identified cluster; a direct consequence of a subsonic flow of hot, shocked wind gas from the O stars in NGC 2244 be ing forced through a channel created by the cluster reported in this L etter.
