SIMBA survey of southern high-mass star forming regions - I. Physical parameters of the 1.2-mm/IRAS sources
MetadatosMostrar el registro completo del ítem
We report the results of a 1.2 mm continuum emission survey toward 146 IRAS sources thought to harbour high-mass star forming regions. The sources have FIR colors typical of UCHII regions and were detected in the CS(2 --> 1) line survey of Bronfman et al. (1996). Regions of 15' x 10', centered on each IRAS source, were mapped with an angular resolution of similar to24", using the SIMBA array on the SEST telescope. 1.2 mm emission was detected toward all IRAS sources. We find that the dust cores associated with these sources have typical sizes of 0.4 pc and masses of 5 x 10(3) M-circle dot. Dust temperatures and luminosities, derived from the SED, are typically 32 K and 2.3 x 10(5) L-circle dot.
