Bipolar molecular outflows in massive star formation regions

Bipolar molecular outflows are a basic component of the star formation process although it has not been well established how outflows from massive stars differ from those from low-mass stars. This thesis presents results from a project to identify bipolar outflows from massive young stellar objects (YSOs) and determine how they compare with low-mass YSOs. In phase I of the project, 122 massive star formation regions were surveyed in...
