Submillimetre observations of a disc around the embedded source GL 490

Abstract

The authors present the results of mapping the 350 μm emission around the bipolar outflow source GL 490. They also report IRAS observations of this source. The 350 μm data show the source to be extended north-south. The authors interpret these results in terms of a disc of dust and gas surrounding the central embedded young star but show that it is incapable of channelling the bipolar molecular outflow. The outflow must therefore be collimated on scales smaller than 1017cm.
