摘要

The massive star forming region IRAS 22267+6244 has been mapped at frequency 110.2 GHz of the molecular line 13CO (J = 1−0). As has been found, the bipolar outflow that was earlier observed for this object in the spectrum of 12CO is also observable in the 13CO line, manifesting itself through a systematic shift of the line profile with distance from the cloud center. Parameters of the bipolar outflow are estimated from emission characteristics of the molecule 13CO. The outflow comprises a sizable fraction of the molecular cloud’s mass. The flow velocity is a linear increasing function of distance from the central source. Comparison of the fast (12CO) and the slow (13CO) parts of the bipolar flow has shown these to be morphologically similar and to possess roughly equal kinetic energies. Estimates are presented of the turbulent kinetic energy and the binding energy in the bipolar flow. The magnitudes are comparable with the total energy of the bipolar outflow.
