Abstract

The IRAS Point Source Catalog has been used to search 482 southern dark clouds for evidence of young stellar objects. Only 6 percent of the selected dark clouds have associated IRAS sources with IRAS colors typical of pre-main-sequence stars. A study of the energy distributions obtained from JHKLM photometry and IRAS flux densities give an identification of these IRAS sources. Thirteen sources have been classified as new low-mass protostellar objects and T Tauri-type stars with nebular surrounding material disks, while four IRAS sources have no evidence of near-IR excesses and appear to be similar to post T Tauri stars in which the nebular disks are probably absent or optically thin. 17 refs.
