cds-question@unistra.frastronomical-modelsstellar-atmospheresearly-type-starsIn this paper we develop a calculation code to account for the effects carried by fast rotation on the observed spectra of early-type stars. Stars are assumed to be in rigid rotation, and the grid of plane-parallel model atmospheres used to represent the gravitational darkening are calculated by means of a non-LTE approach. Attention is paid to the relation between the apparent and parent non-rotating counterpart stellar fundamental parameters and apparent, and true Vsini parameters as a function of the rotation rate Omega/Omega_c_, stellar mass, and inclination angle. It is shown that omitting of gravitational darkening in the analysis of chemical abundances of CNO elements can produce systematic overestimation or underestimation, depending on the lines used, rotational rate, and inclination angle.2005A&A...440..305Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/440/305CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/440/305https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/440/305http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/440/305https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/440/305https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/440/305http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/440/305GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/440/305/table9 (Apparent and parent non-rotating counterpart (pnrc) fundamental parameters of the studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/440/305/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/440/305/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/440/305/table9?GETtext/xml+votable180.050000true1.610583164.19616860.0055555555555555566/405 463 472 474 1011 1196 1392 1586 1748 1769 1784 2017 2775 2849 2884 3030 3067 3316 3491 3597 6846 9054 9686 9836 11959 12659 12766 12988 13017 13042 13292 13559 13687 13701 13721 14108 14396 14555 14622 14631 14638 15250 15365 15375 15479 15580 15768 15778 18915 19017 19202 19402 20419 20609 20800 21324 21365 21447 21515 21644 21893 22054 22235 22254 22334 22503 22517 22579 22615 22637 22837 22895 23646 23775 23851 23963 24142 24179 24183 24363 26672 29040 29893 30330 30476 30722 30818 31759 37253 37330 37364 37776 37887 39397 39671 39679 39704 39715 39806 39863 39922 40221 40242 41171 41740 41866 41943 42273 42279 42948 43024 43038 43062 43310 43365 43407 43531 43689 44316 44502 46081 47021 47033 47056 47121 47246 48534https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/440/305?format=asciidefaultJ/A+A/440/305/table9Apparent and parent non-rotating counterpart (pnrc) fundamental parameters of the studied starse_Teffrms uncertainty on TeffKstat.error;phys.temperature.effectiveintrecnoRecord number assigned by the VizieR team.
