cds-question@unistra.fryoung-stellar-objectsspectroscopyOutflows are an important part of the star formation process as both the result of ongoing active accretion and one of the main sources of mechanical feedback on small scales. Water is the ideal tracer of these effects because it is present in high abundance for the conditions expected in various parts of the protostar, particularly the outflow. We constrain and quantify the physical conditions probed by water in the outflow-jet system for Class 0 and I sources. We present velocity-resolved Herschel HIFI spectra of multiple water-transitions observed towards 29 nearby Class 0/I protostars as part of the WISH guaranteed time key programme. The lines are decomposed into different Gaussian components, with each component related to one of three parts of the protostellar system; quiescent envelope, cavity shock and spot shocks in the jet and at the base of the outflow. We then use non-LTE radex models to constrain the excitation conditions present in the two outflow-related components.2014A&A...572A..21Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/572/A21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/572/A21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/572/A21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/572/A21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/572/A21https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/572/A21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/572/A21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/572/A21/table1 (Source parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/572/A21/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/572/A21/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/572/A21/table1?GETtext/xml+votable180.050000true51.41208330.7348330.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/572/A216/859 862 1052 1054 1154 15965 23549 29653 30366 30519 30733 32083 36956 37819 41132 42738 42981 42992 43010 47828https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/572/A21?format=asciiOpticaldefaultJ/A+A/572/A21/table1Source parametersSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
