We have detected emission at 10.4 μ m (N band) and at 24.8 μ m from the high mass protostar candidate IRAS 18089-1732 with the MIRSI camera on the IRTF. Emission was detected within an arcsecond of a mm and sub-mm dust continuum peak at which there are an H2O maser and a hypercompact HII region (HC HII). This source was also detected by IRAC on Spitzer in the GLIMPSE survey.
Two sources, A & B, were detected in both MIRSI filters, and all IRAC bands. The brighter N band source, A, was registered to the IRAC 8 μ m position for astrometry. It is at the position of an MSX source, 10\arcsec NW of the H2O/HC HII/smm position. The fainter N band source, B, is within an arcsec of the H2O/HC HII/smm position. It is brighter than A at 24.8 μ m.
The 24.8 μ m emission of source B is offset E of the N band emission, and is extended about 2\farcs5 N-S (marginally resolved on the IRTF). The extension is roughly parallel to the SiO outflow axis. The CH3OH maser located 1\farcs5 to the SW is apparently outside the mid-ir peak. The SED of source B rises from 3.4 mJy at 3.6 μ m to 6.1 (+/- 3) Jy at 24.8 μ m, with an apparent silicate absorption in N band, suggesting that the source is deeply embedded.
The IRTF is operated by the University of Hawaii supported by NASA under Cooperative Agreement NCC5-538 issued through the OSS Planetary Astronomy Program.
