Bipolar outflow

WebThe high-velocity CO wings show a clear bipolar structure and are localized within 0.2 pc of a central infrared source IRAS 05338-0624. The outflow is associated with a dense cloud that is significantly elongated in the same direction as the outflow axis, contrary to what is expected for disk collimation of the bipolar outflow.
