Submillimeter Array multiline observations of the massive star-forming region IRAS 18089-1732
H. Beuther, Q. Zhang, T. R. Hunter +8
Submillimeter Array (SMA) observations of the high-mass star-forming region IRAS 18089-1732 in the 1 mm and 850 m band with 1 GHz bandwidth reveal a wealth of information. We pr…
Search for Calibrators for the Submillimeter Array: I. High-Mass Star Forming Regions
Y. -N. Su, S. -Y. Liu, J. Lim +8
We present initial results of an ongoing search for interferometric calibrators at submillimeter (sub-mm) wavelengths with the Submillimeter Array (SMA). Powerful radio galaxies ar…
Mapping the Outflow from G5.89-0.39 in SiO(5-4)
P. K. Sollins, T. R. Hunter, J. Battat +9
We have mapped the ultracompact HII region, G5.89-0.39, and its molecular surroundings with the Submillimeter Array at 2".8 x 1".8 angular resolution in 1.3 mm continuum, SiO(5-4),…
Submillimeter Array Observations of CS J=14--13 Emission from the Evolved Star IRC+10216
K. H. Young, T. R. Hunter, D. J. Wilner +1
We present imaging observations of the evolved star IRC+10216 in the CS J=14--13 line at 685.4 GHz and associated submillimeter continuum at about 2'' resolution made with the part…
SMA outflow/disk studies in the massive star-forming region IRAS18089-1732
H. Beuther, T. R. Hunter, Q. Zhang +8
SMA observations of the massive star-forming region IRAS 18089-1732 in the 1mm and 850mu band reveal outflow and disk signatures in different molecular lines. The SiO(5--4) data sh…
The Circumstellar Environments of High-Mass Protostellar Objects I: Submillimetre Continuum Emission
S. J. Williams, G. A. Fuller, T. K. Sridharan
We present maps of the 850 micron and 450 micron continuum emission seen towards a sample of 68 high-mass protostellar candidates with luminosities ranging from 10^2.5 to 10^5 sola…
