Session 108 - HII Regions.
Display session, Thursday, January 18
North Banquet Hall, Convention Center
We present diffraction-limited 350 \mum images of ultracompact HII regions (UCHIIs) obtained at the Caltech Submillimeter Observatory during engineering observations with our new 24-pixel bolometer array camera (SHARC) built in collaboration with the Goddard Space Flight Center. With a beamsize of 10'', our images show that the 350 \mum emission from these sources is generally quite compact. We combine our submillimeter fluxes with IRAS fluxes from a HiRes survey of UCHIIs and estimate the dust temperature, luminosity and mass of these regions. We also present CO J=3\rightarrow2 maps of molecular outflows emerging from several of these active sources including K3-50, G138.30+1.56, and G240.31+0.07.
