Abstract
Mapping observations were made towards IRAS 20110+3321 using theNobeyama 45 m and the Delingha 13.7 m radio telescopes. The highangular resolution (~21′′) image with the 45 m telescope showsthat 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 mechanicalluminosity than those from low mass YSOs, indicating that the outflow isdriven by the IRAS source. A dense massive core was detected by mappingC18O (J = 1−0) line in the area with the 13.7 m telescope. TheIRAS source lies within the core but slightly offsets from its emissionpeak.
