High-Resolution Observations of Molecular Lines toward the Hot Core G28.20-0.04N

TL;DR

This study uses high-resolution observations at 1.3 mm to analyze molecular lines in the hot core G28.20-0.04N, revealing outflows, possible rotation, and the hot core's properties.

Contribution

First detailed arcsecond resolution mapping of multiple molecular lines in G28.20-0.04N, providing insights into its hot core, outflows, and kinematic features.

Findings

Detection of hot core associated with G28.20-0.04N

Identification of outflow and possible rotation

Mapping of various molecular lines

Abstract

We present the results from arcsecond resolution observations of various line transitions at 1.3 mm toward hypercompact HII region G28.20-0.04N. With the SMA data, we have detected and mapped the transitions in the CH$_{3}$CN, CO, $^{13}$CO, SO$_{2}$, OCS, and CH$_{3}$OH molecular lines as well as the radio recombination line H30$\alpha$. The observations and analysis indicate a hot core associated with G28.20-0.04N. The outflow and possible rotation are detected in this region.
