Abstract

We have analyzed the temperature and column density around the S140 cluster of young stellar objects by combining Herschel PACS and HIFI observations with ground-based mapping observations of mm-wave lines and continuum. We also compare the spatial distribution of gas and dust temperatures and find significant differences between them. The velocity information in the lines allows us to separate the quiescent component from outflows when deriving the gas temperature and column density. From the mapping observations of multiple 13CO transitions we perform an LTE analysis via rotation diagrams. A detailed comparison of the conditions at the position of IRS 1 and at the ionization front, close to the submm peak, shows very different chemical compositions and excitation temperatures.
