Description

CO observations of the molecular cloud complex in the vicinity of IC 5146 reveal three regions of enhanced emission, all lying around the periphery of the Sharpless region S125. The most intense region has a peak CO line temperature of 41 K. The continued existence of this hot spot can be accounted for by an embedded protostar of luminosity class between B0.5 and B1. A comparison with H I observations of about the same spatial and velocity resolution shows that the surrounding H I cloud emission is generally strong where the CO emission is weak
