Physics

Scientific paper

Mapping observations were made towards IRAS 20110+3321 using the Nobeyama 45 m and the Delingha 13.7 m radio telescopes. The high angular resolution (~21'') image with the 45 m telescope shows that there is a high-velocity bipolar molecular outflow in this region, which is in the NW SE direction with a collimation factor of ~ 2.2. The outflow has significantly higher mass loss rate and mechanical luminosity than those from low mass YSOs, indicating that the outflow is driven by the IRAS source. A dense massive core was detected by mapping C18O (J = 1-0) line in the area with the 13.7 m telescope. The IRAS source lies within the core but slightly offsets from its emission peak.
