Scientific paper

High spatial resolution 50 and 100 microns observations of the active star-forming region RCW 122C show that the far-infrared emission from RCW 122C is resolved into two separate sources, RCW 122C I and II, which correspond to the radio continuum sources seen by the VLA (Gaume & Mutel). The dust temperatures are 32 and 34 K, and the far-infrared luminosities are 9.1 × 104 Lsun and 5.6 × 104 Lsun for RCW 122C I and II, respectively. The bolometric luminosities correspond to two zero-age main-sequence stars of types O7 and 08.5 for RCW 122C I and II, respectively. These stars are deeply embedded in the surrounding molecular clouds, with visual extinctions of ≍48 and ≍32 mag, respectively.
