cds-question@unistra.frgiant-starsspectroscopyWe aim to investigate the physical and chemical properties of the molecular envelope of the oxygen-rich AGB star IK Tau. We carried out a millimeter wavelength line survey between ~79 and 356GHz with the IRAM-30m telescope. We analysed the molecular lines detected in IK Tau using the population diagram technique to derive rotational temperatures and column densities. We conducted a radiative transfer analysis of the SO_2_ lines, which also helped us to verify the validity of the approximated method of the population diagram for the rest of the molecules.2017A&A...597A..25Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/597/A25CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/597/A25https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/597/A25http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/597/A25https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/597/A25https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/597/A25http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/597/A25GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/597/A25/list (List of fits spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/597/A25/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/597/A25/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/597/A25/list?GETtext/xml+votable180.050000true58.3701711.406280.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/597/A256/23471https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/597/A25?format=asciidefaultJ/A+A/597/A25/so2levelEnergy levelsrecnoRecord number assigned by the VizieR team.
