cds-question@unistra.frastronomical-modelsmolecular-cloudschemical-abundancesBecause of new telescopes that will dramatically improve our knowledge of the interstellar medium, chemical models will have to be used to simulate the chemistry of many regions with diverse properties. To make these models more robust, it is important to understand their sensitivity to a variety of parameters. In this article, we report a study of the sensitivity of a chemical model of a cold dense core, with homogeneous and time-independent physical conditions, to variations in the following parameters: initial chemical inventory, gas temperature and density, cosmic-ray ionization rate, chemical reaction rate coefficients, and elemental abundances.2010A&A...517A..21Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/517/A21CatalogResearchIsServedByTAP VizieR generic servicerelated-tohttp://www.physics.ohio-state.edu/~eric/research.html : OSU Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/517/A21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/517/A21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/517/A21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/517/A21https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/517/A21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/517/A21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/517/A21/osuosu_03_2008 chemical networkrecnoRecord number assigned by the VizieR team.
