Scientific paper

Observations of carbon monoxide and formyl emission from the molecular cloud IRAS 20188+3928 reveal it to possess a compact core from which emanates a very dense bipolar molecular outflow. From the CO observations it is deduced that the outflow has a mean molecular hydrogen density ≡7.5×103/D cm-3 (where D is its distance in kpc) while the HCO+ emission arises from clumps within the flow of density ≡5×105cm-3. The derived properties of the outflow are very similar to those of the flows in the well known sources Cepheus A and NGC 2071.
