The bipolar outflow associated with NGC 2071 reflection nebula

Abstract

We observed the molecular outflow associated with NGC 2071 reflection nebula using 14m DRAO telescope. We used the lowest rotational transition lines of 12CO, 13CO, and C 18O and J = 2-1 of CS. The line profiles of 12CO have strong dips around the line center velocity which are the strongest in the center position and are weaker outside. The blue shifted outflows in the NE-direction and the red shifted ones in the SW-direction of the center position from the integration maps of the line wings of 12CO were observed. 13CO showed the bipolar outflow, which is similar to that of 12CO in the shape and the direction. From the channel map of 13CO, we determined the velocity extents representing flow materials and examined the dense disklike materials, which are similar to the outflow in size but distributed perpendicular to the major axis of the bipolar outflow.
