| 英文摘要 | We present the results of a high-resolution study with the Submillimeter Array (SMA) toward the massive star-forming complex G20.08-0.14N. With the SMA data, we have detected and analyzed the transitions in the (CO)-C-12 (3-2) and (CO)-C-12 (2-1) molecular lines as well as CH3CN. The millimeter observations reveal highly collimated bipolar molecular outflows, traced by high-velocity (CO)-C-12 (2-1) and (CO)-C-12 (3-2) emissions. Using a rotation temperature diagram, we derive that the rotational temperature and the column density of CH3CN are 244 K and 1.2x10(15) cm(-2), respectively. We also suggest that the minor outflow is probably driven by the hypercompact (HC) HII region A that is inside. We find the molecular gas (traced by (CO)-O-17, SO, CH3OH and SO2) surrounding G20.08-0.14N appears to be undergoing bulk rotation. The HCHII region A that is inside is most probably the main source of accretion and heating for G20.08-0.14N. |
