Abstract:
We report the results of a 1.2mm 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, Cat. J/A+AS/115/81).
Regions of 15'x10', centered on each IRAS source, were mapped with an
angular resolution of ∼24", using the SIMBA array on the SEST
telescope. 1.2mm emission was detected toward all IRAS sources. We
find that the dust cores associated with these sources have typical
sizes of 0.4pc and masses of 5x103M_☉. Dust temperatures and
luminosities, derived from the SED, are typically 32K and
2.3x105L☉.
Description:
The observations were made using the 37-channel hexagonal bolometer
array SIMBA installed at the SEST 15m telescope. The passband of the
bolometer has an equivalent width of 90GHz and is centered at 250GHz.
The SEST telescope has a beamwidth of 24" at the frequency band of
SIMBA. The 1.2mm emission was mapped toward 146 regions, centered on
IRAS sources.
