Abstract

The NANTEN2-4 m submillimeter telescope was used to map the [C i] ³P₁-³PP₀, ³P₂-³P₁ and CO 4–3, 7–6 lines in two 4'×4' regions of Carina where molecular material interfaces with radiation from the massive star clusters. These data were combined with ¹³CO SEST spectra, HIRES/IRAS maps at 60 µm, 100 µmm, maps of 8 µmm IRAC/Spitzer, and of MSX emission. We use PDR models to interpret the observed far-infrared and submillimeter emission, assuming that all observed emission stems from an ensemble of spherically symmetric PDR clumps.
