Scientific paper

The results of a survey of bright IRAS point sources along the southern Milky Way are presented. The survey was designed to search in the near infrared for new examples of young stellar objects, many of whose northern counterparts are responsible for driving bipolar outflows in molecular clouds. Photometry in the J, H, and K bands is given for nearly all of the 113 near-infrared sources that were found to be associated with the candidate IRAS sources, L magnitudes are given for 60, and M magnitudes for 14. Positions accurate to ≤2arcsec are presented for all the objects detected at K. Forty-five new YSO candidates have been found; the remaining IRAS objects are probably field stars suffering heavy extinction. Deep i band (8000 Å) CCD frames are presented for most of the prime YSO candidates. These are used to examine the surroundings of each source for associated stars and nebulosity; at least half of the candidates have associated optical objects. Low-resolution spectrophotometry in the 2.2 μm region of 15 of the primary candidates confirm that none is a compact H II region or late-type star.
