Abstract

We present the results from arcsecond resolution observations of various line transitions at 1.3 mm toward hypercompact H II region G28.20-0.04N. With the SMA data, we have detected and mapped the transitions in the CH 3CN, CO, 13CO, SO2, OCS, and CH3OH molecular lines as well as the radio recombination line H30α. The observations and analysis indicate a hot core associated with G28.20-0.04N. The outflow and possible rotation are detected in this region.
