cds-question@unistra.fratomic-physicsspectroscopyastronomical-modelsstellar-atmospherespeculiar-variable-starsThe spectra of B-type and early A-type stars show numerous unidentified lines in the whole optical range, especially in the 5100-5400{AA} interval. Because FeII transitions to high energy levels should be observed in this region, we used semiempirical predicted wavelengths and gf-values of FeII to identify unknown lines. Semiempirical line data for FeII computed by Kurucz are used to synthesize the spectrum of the slow-rotating, Fe - overabundant CP star HR6000.2010A&A...520A..57Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/520/A57CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/102/607 : Stark widths of FeII lines (Puric+ 1993)J/A+A/293/953 : IRON project VI.
