[63.02] The Collimated Bipolar Outflow of OH231.8+4.2

D. Fong, M. Meixner (U. of Illinois)

We present high resolution (5") CO J=1-0 line observations of the bipolar nebula OH231.8+4.2 taken with the BIMA millimeter array. The integrated CO intensity map reveals a highly collimated molecular jet along the polar axis, aligned with the red and blue-shifted bipolar lobes. A constant velocity gradient along the entire length of the bipolar axis is also seen. The de-projected CO outflow velocity exceeds 120 km/s which suggests a dynamical age of 900 years.
