cds-question@unistra.frvariable-starscarbon-starsspectroscopyA spectral line survey of IRC +10216 between 13.3 and 18.5GHz was carried out using the Shanghai Tian Ma 65 m Radio Telescope (TMRT-65m) with a sensitivity of <7mK. Thirty-five spectral lines of 12 different molecules and radicals were detected in total. Except for SiS, the detected molecules are all carbon-chain molecules, including HC_3_N, HC_5_N, HC_7_N, HC_9_N, C_6_H, C_6_H^-^, C_8_H, SiC_2_, SiC_4_, c-C_3_H_2_, and l-C_5_H. The presence of rich carbon-bearing molecules is consistent with the identity of IRC +10216 as a carbon-rich asymptotic giant branch (AGB) star. The excitation temperatures and column densities of the observed species are derived by assuming a local thermodynamic equilibrium and homogeneous conditions.2017A&A...606A..74Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/606/A74CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/330/676 : IRC+10216 Silicon and sulfur chemistry (Willacy+ 1998)J/ApJS/177/275 : 1.3 and 2mm survey of IRC+10216 (He+, 2008)J/ApJ/688/L83 : Detection of C_5_N^-^ in IRC +10216 (Cernicharo+, 2008)J/ApJS/190/348 : 1mm spectral survey of IRC+10216 + VY CMa (Tenenbaum+, 2010)J/ApJS/193/17 : Spectral-line survey of IRC+10216 at 293-355GHz (Patel+, 2011)J/A+A/545/A12 : Chemistry of IRC+10216 inner wind modelled (Cherchneff, 2012)J/A+A/574/A56 : IRC +10216 17.8GHz-26.3GHz spectrum (Gong+, 2015)J/ApJ/806/L3 : Disilicon carbide (SiCSi) in CW Leo (Cernicharo+, 2015)J/A+A/601/A4 : IRC+10216 carbon chains mapped with ALMA (Agundez+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/606/A74https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/606/A74http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/606/A74https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/606/A74https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/606/A74http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/606/A74GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/606/A74/list (List of spectra in irc10216.fit file)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/606/A74/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/606/A74/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/606/A74/list?GETtext/xml+votable180.050000true146.9893713.278850.0055555555555555566/4365https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/606/A74?format=asciiOpticaldefaultJ/A+A/606/A74/listList of spectra in irc10216.fit filespShow the spectrummeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
