Scientific paper

The luminosities in excess of 1,000,000 solar luminosities obtained in the present 1-arcmin resolution mapping of the two southern H II regions RCW 122 and G 351.6-1.3 requires the presence of OB star clusters. A luminosity/unit mass of the associated cloud of about 6 solar luminosities/solar mass is obtained by combining near-IR, far-IR, and CO-emission properties for RCW 122, and it is determined that the emitting dust grains are amorphous silicate-like. G 351.6-1.3 has very similar properties, although the fraction of 1-25 micron luminosity corrected for silicate absorption is about five times less than for RCW 122.
