cds-question@unistra.frspectroscopycarbon-starsradio-spectroscopyWe report a spectral-line survey of the extreme carbon star IRC+10216 carried out between 293.9 and 354.8GHz with the Submillimeter Array. A total of 442 lines were detected, more than 200 for the first time; 149 are unassigned. Maps at an angular resolution of ~3" were obtained for each line. A substantial new population of narrow lines with an expansion velocity of ~4km/s (i.e., ~30% of the terminal velocity) was detected. Most of these are attributed to rotational transitions within vibrationally excited states, emitted from energy levels above the {nu}=0, J=0 ground state with excitation energy of 1000-3000K. Emission from these lines appears to be centered on the star with an angular extent of <1". We use multiple transitions detected in several molecules to derive physical conditions in this inner envelope of IRC+10216.2011ApJS..193...17Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/193/17CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/190/348 : 1mm spectral survey of IRC+10216 + VY CMa (Tenenbaum+, 2010)J/ApJS/186/406 : 350um polarimetry from CSO (Dotson+, 2010)J/ApJS/175/277 : Submillimeter-Continuum SCUBA detections (Di Francesco+, 2008)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/A+AS/142/181 : 2mm molecular line survey of IRC+10 216 (Cernicharo+, 2000)J/A+A/330/676 : IRC+10216 Silicon and sulfur chemistry (Willacy+, 1998)J/A+A/317/503 : Photometric + visibility data of IRC +10 216 (Groenewegen,https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/193/17https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/193/17http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/193/17https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/193/17https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/193/17http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/193/17GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapMillimeterdefaultJ/ApJS/193/17/table2Parameters of the lines detected in IRC+10216 in the Submillimeter Array (SMA) line surveynuCat?
