cds-question@unistra.fratomic-physicsspectroscopyStark broadening parameters have been calculated for 60 spectral lines of XeVIII, for broadening by electron, proton, and HeIII impacts. For calculations, the semiclassical perturbation approach in the impact approximation has been used. The widths and shifts are provided for temperatures from 20000 K to 500000 K and for an electron density of 10^17^/cm^3^. Obtained results have been used to study the influence of Stark broadening on spectral lines in DO white dwarf atmospheres and it has been found that exist broad layers where this broadening mechanism is dominant in comparison with thermal Doppler broadening.2015MNRAS.454.1736Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/454/1736CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/116/359 : Xe II lines Stark broadening (Popovic+, 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/454/1736https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/454/1736http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/454/1736https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/454/1736https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/454/1736http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/454/1736GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/MNRAS/454/1736/table1Stark broadening parameters for Xe VIII spectral lines, for a perturber density of 10^17^/cm^3^recnoRecord number assigned by the VizieR team.
