cds-question@unistra.frpre-main-sequence-starsinfrared-astronomyWe present SOFIA/FIFI-LS observations of three Class 0 and one Class I outflows (Cep E, HH 1, HH 212, and L1551 IRS5) in the far-infrared [OI]63um and [OI]145um transitions. Spectroscopic [OI]63um maps enable us to infer the spatial extent of warm (T~500-1200K), low-excitation atomic gas within these protostellar outflows. Our main goal is to determine mass-loss rates from the obtained [OI]63um maps and compare these with accretion rates from other studies. The far-infrared [OI]63um emission line is predicted to be the main coolant of dense, dissociative J-shocks caused by decelerated wind or jet shocks. If proper shock conditions prevail, the instantaneous mass-ejection rate is directly connected to the [OI]63um luminosity. In order to unravel evolutionary trends we analyse a set of 14 Class 0/I outflow sources that have been spatially resolved in the [OI]63um emission. We compare these data with a sample of 74 Class 0/I/II outflow sources that have been observed with Herschel (WISH, DIGIT, WILL, GASPS surveys) without spatially resolving the [OI]63um line.2021A&A...650A.173Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/650/A173CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/642/A216 : Five Herbig-Haro objects SOFIA/FIFI-LS images (Sperling+ 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/650/A173https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/650/A173http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/650/A173https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/650/A173https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/650/A173http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/650/A173GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/650/A173/list (List of fits images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/650/A173/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/650/A173/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/650/A173/list?GETtext/xml+votable180.050000true345.845661.706950.0055555555555555566/14315 21436 22866 23549https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/650/A173?format=asciiInfrareddefaultJ/A+A/650/A173/listList of fits imagesrecnoRecord number assigned by the VizieR team.
