cds-question@unistra.fryoung-stellar-objectsspectroscopyThe gas-solid budget of carbon in protoplanetary disks is related to the composition of the cores and atmospheres of the planets forming in them. The principal gas-phase carbon carriers CO, C^0^, and C^+6 can now be observed regularly in disks. The gas-phase carbon abundance in disks has thus far not been well characterized observationally. We obtain new constraints on the [C]/[H] ratio in a large sample of disks, and compile an overview of the strength of [CI] and warm CO emission. We carried out a survey of the CO 6-5 line and the [CI] 1-0 and 2-1 lines towards 37 disks with the APEX telescope, and supplemented it with [CII] data from the literature. The data are interpreted using a grid of models produced with the DALI disk code. We also investigate how well the gas-phase carbon abundance can be determined in light of parameter uncertainties.2016A&A...588A.108Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/588/A108CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/588/A108https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/588/A108http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/588/A108https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/588/A108https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/588/A108http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/588/A108GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/588/A108/list (List of fits spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/588/A108/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/588/A108/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/588/A108/list?GETtext/xml+votable180.050000true68.7308324.481390.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/588/A1086/599 1050-1051 1114 1168-1169 1171 21480 22023 23548-23549 24279 28762 28921 30741 31259 34762 36948 36956-36957 37186 37978 38382 41472 42595 42611 42644 42704 42981 44379https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/588/A108?format=asciiOpticaldefaultJ/A+A/588/A108/listList of fits spectrarecnoRecord number assigned by the VizieR team.
