Scientific paper

Following a previous study of accelerated and constant velocity fields, CO line formation in decelerated bipolar flows is now investigated. Position-velocity diagrams and integrated intensity maps are presented for four spatial configurations. These results are used together with previous computations to put constraints on the velocity field and the large-scale structure of observed flows. It is suggested that observations might be best explained by a model involving filled CO lobes with a bright, accelerated, high-velocity core surrounded by a slower, low-emissivity envelope.
