MID-INFRARED PHOTOMETRY AND SPECTRA OF THREE HIGH-MASS PROTOSTELLAR CANDIDATES AT IRAS 18151-1208 AND IRAS 20343+4129

摘要

We present arcsecond-scale mid-IR photometry (in the 10.5 μm N band and at 24.8 μm), and low-resolution spectra in the N band(R ≌ 100) of a candidate high-mass protostellarobject(HMPO)in IRAS 18151-1208 and of two HMPO candidates in IRAS 20343+4129, IRS 1
