cds-question@unistra.frvariable-starsspectroscopyOur knowledge of the chemical properties of the circumstellar ejecta of the most massive evolved stars is particularly poor. We aim to study the chemical characteristics of the prototypical yellow hypergiant star, IRC +10420. For this purpose, we obtained full line surveys at 1 and 3mm atmospheric windows. We have identified 106 molecular emission lines from 22 molecular species. Approximately half of the molecules detected are N-bearing species, in particular HCN, HNC, CN, NO, NS, PN, and N_2_H. We used rotational diagrams to derive the density and rotational temperature of the different molecular species detected. We introduced an iterative method that allows us to take moderate line opacities into account.2016A&A...592A..51Qhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/592/A51CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/592/A51https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/592/A51http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/592/A51https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/592/A51https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/592/A51http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/592/A51GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/592/A51/list (List of spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/592/A51/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/592/A51/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/592/A51/list?GETtext/xml+votable180.050000true291.711.354720.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/592/A516/30664https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/592/A51?format=asciidefaultJ/A+A/592/A51/listList of spectrarecnoRecord number assigned by the VizieR team.
