Abstract

We have observed the molecular outflow associated with the HH 111 optical jet at 6″ resolution in the COJ = 1-0 transition using the Berkeley-Illinois-Maryland Millimeter Array. Both the CO kinematics and morphology indicate a striking hollow tubular structure surrounding the optical jet. The velocity component parallel to the jet increases with distance from the central star more rapidly than the component perpendicular to the jet. The data place constraints on jet-driven models for molecular outflows. The kinematics and structure are consistent with recent wide-angle, radial wind models.
