Protostellar candidates in southern molecular clouds.

Abstract (from CDS):
In the course of an extensive 1300µm 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 strong 1300µm fluxes, points towards these objects being either protostars or prestellar clumps, rather than pre-main sequence stars. Some of these protostellar candidates have several components, suggesting the possibility that they may represent simultaneous formation of multiple stars. Cha-MMS1 is located between the lobes of a small compact, already 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 major, already known molecular outflow in the northern part of the Chamaeleon I cloud complex. Cir-MMS1 is located in a massive cloud core between the lobes of a major, already known molecular outflow in a large cloud complex in Circinus. B59-MMS1 is found in the little-studied molecular cloud B59, and Sco-MMS1 is embedded in an anonymous Bok globule in Scorpius.
