Abstract (from CDS):

We present ISO SWS (AOT6) observations of the protostellar object RAFGL 7009S. This source is particularly interesting for the characterisation of chemistry arising from grain surfaces and mantles, since the solid state features of many simple molecules such as H₂O, CO, CO₂, ¹³CO₂ and CH₄ are detected, together with weaker features not yet unambiguously identified. Gas phase H₂O, CO₂, CH₄ and CO can also be seen superimposed on the much broader solid state features. We derive an estimate for the gas phase temperature around 50K. The gas to solid ratios of these simple molecules is found to be ≥0.2 for H₂O, ∼0.2 for CH₄, and an order of magnitude lower for CO₂. We discuss the possible implications for interstellar chemistry in such objects.
