Description

Radioastronomy maps are presented from 16 arcsec resolution scans of the C-12O J = 1 yields 0 emission from S140 IRS, an H II region that is also associated with star formation. The observed C-12O outflow exhibits clear bipolarity. Integral values are calculated for the total mass, momentum and energy of the outflow, which has a velocity asymmetry that features the lowest velocity in the region of greatest mass outflow. Possible explanations for the velocity/mass outflow asymmetry are considered. 37 references
