cds-question@unistra.frspectroscopybe-starsastronomical-modelsWe present a set of theoretical H{alpha} emission-line profiles of Be stars, created by systematically varying model input parameters over a wide range of accepted values. Models were generated with a non-LTE radiative transfer code that incorporates a non-isothermal disk structure and a solar-type chemical composition. The theoretical H{alpha} emission-line profiles were compared to a large set of Be star spectra with the aim of reproducing their global characteristics. We find that the observed profile shapes cannot be used to uniquely determine the inclination angle of Be star+disk systems. Drastically different profile shapes arise at a given inclination angle as a direct result of the state of the gas, and self-consistent disk physical conditions are therefore crucial for interpreting the observations.2010ApJS..187..228Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/187/228CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/187/228https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/187/228http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/187/228https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/187/228https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/187/228http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/187/228GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/187/228/table3 (Representative models)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/187/228/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/187/228/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/187/228/table3?GETtext/xml+votable180.050000true1.610586764.19616890.0055555555555555566/463 472 474 1196 1460 1725 1748 1769 1784 2017 2775 2849 2884 3030 3067 3316 3491 3597 3737 9686 9836 11959 12461 12659 13268 13687 14108 14631 14855 15372 15375 15479 18915 19017 19202 19402 21324 21515 21646 22334 22579 22637 22895 22911 23851 23963 24142 24179 24266 24969 26672 28921 29207 30403 30722 31259 31759 32065 39397 39671 39806 39863 40221 40242 42483 43365 43407 44360 48534https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/187/228?format=asciiOpticaldefaultJ/ApJS/187/228/table3Representative modelsn_EWHaObserved H{alpha} line profile shape (3)meta.notecharrecnoRecord number assigned by the VizieR team.
