cds-question@unistra.fratomic-physicsFor the spectral analysis of high-resolution and high-signal-to-noise (S/N) spectra of hot stars, state-of-the-art non-local thermodynamic equilibrium (NLTE) model atmospheres are mandatory. These are strongly dependent on the reliability of the atomic data that is used for their calculation. In a recent analysis of the ultraviolet (UV) spectrum of the DA-type white dwarf G191-B2B, 21 ZnIV lines were newly identified. Because of the lack of ZnIV data, transition probabilities of the isoelectronic GeVI were adapted for a first, coarse determination of the photospheric Zn abundance. Reliable ZnIV and ZnV oscillator strengths are used to improve the Zn abundance determination and to identify more Zn lines in the spectra of G191-B2B and the DO-type white dwarf RE 0503-289.2014A&A...564A..41Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/564/A41CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/546/A55 : Ge V and Ge VI oscillator strengths (Rauch+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/564/A41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/564/A41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/564/A41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/564/A41https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/564/A41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/564/A41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/564/A41/table1Data for ZnIVrecnoRecord number assigned by the VizieR team.
