CO and radio continuum emission has been observed in the direction of 39 bright 100-micron sources from the IRAS point source catalog in an attempt to better understand the early stages of star formation. All 39 sources are found to be associated with molecular clouds and are generally characterized by high temperatures (15-40 K) and wide wings in the profiles (up to 34 km/s). Twenty-six of the 39 sources show wide (C-12)O lines, which are interpreted as a result of gas outflow associated with star formation processes. Of the 24 sources for which distances and 6-cm flux densities can be assigned, 11 are premain sequence objects, and 4 others are possibly in this category. Six of the eleven premain sequence sources have associated continuum emission. 30 refs. |
