| Abstract: | Comparison of submillimetre continuum observations of the L1204/S140 complex with previous high resolution CS, NH3 and CI observations provides evidence that, for the first time, demonstrates the PDR and outflow are intimately linked. The only scenario that is able to explain all of the available molecular and atomic emission line data and our submillimetre continuum data, is one in which the outflow has expanded towards the edge of the molecular cloud and the edge of the blueshifted outflow lobe is now bounded by the expanding HII region. The NH3 and continuum emission emanate from the inner edge of the outflow lobe, shielded from the external UV field. |
