A survey of the SO JK=10-01Transition toward massive star-forming regions.

MATEEN M., HOFNER P. and ARAYA E.

Abstract (from CDS):

We present the most extensive survey to date of the SO ground state transition JK=10-01(30 GHz). We observed 49 regions of massive star formation with the Max-Planck-Institut für Radioastronomie (MPIfR) 100 m telescope. In addition, the SO JK=43-32transition was observed with the IRAM 30 m telescope toward a subsample of seven sources. Emission in the SO JK=10-01transition most likely arises from the parsec-scale molecular clumps surrounding ultracompact H II regions. In general, the SO JK=10-01 line has a Gaussian shape and appears to be optically thin. We derive SO column densities between 0.58x1014 and 12x1014/cm2 and SO abundances in the range 0.18x10–9-4.4x10–9. Our observations show that the SO ground state transition is an effective tool to study massive star-forming clumps, and the data presented in this paper provide a useful supplement for future multitransition SO studies.
