cds-question@unistra.fratomic-physicsgiant-starsWe present a dynamical and chemical model of the inner wind of the carbon-rich, AGB star IRC+10216. We include the effect of pulsation-driven shocks on the gas envelope close to the stellar photosphere and construct an extended chemical model that includes in particular the chemistry of hydrocarbon species and silicon and sulphur-bearing molecules. The derived theoretical abundances for many molecules are in excellent agreement with values obtained from observations of infrared ro-vibrational molecular lines. We confirm the ``parent'' character of certain chemical species and show that the inner wind of IRC+10216, and more generally of evolved AGB stars, is an active dynamical and chemical region where molecules are formed and processed.1998A&A...330..676Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/330/676CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/330/676https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/330/676http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/330/676https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/330/676https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/330/676http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/330/676GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/330/676/table5The reaction setrecnoRecord number assigned by the VizieR team.
