Abstract
In the course of an extensive 1300 mu m mapping survey of star forming regions in southern molecular clouds, we have identified five regions which contain new protostellar candidates. The objects are generally separated from nearby known IRAS sources. This, together with their st rong 1300 mu m fluxes, points towards these objects being either proto stars or prestellar clumps, rather than pre-main sequence stars. Some of these protostellar candidates have several components, suggesting t he possibility that they may represent simultaneous formation of multi ple stars. Cha-MMS1 is located between the lobes of a small compact, a lready known molecular outflow in the Ced 110 region of the Chamaeleon I molecular cloud, and is a likely candidate as the driving source of the nearby HH 49/50 objects. Cha-MMS2 lies between the lobes of a maj or, already known molecular outflow in the northern part of the Chamae leon I cloud complex. Cir-MMS1 is located in a massive cloud core betw een the lobes of a major, already known molecular out-flow in a large cloud complex in Circinus. B59-MMS1 is found in the little-studied mol ecular cloud B59, and Sco-MMS1 is embedded in an anonymous Bok globule in Scorpius.
