cds-question@unistra.frchemically-peculiar-starsline-intensitiesElemental abundances analysis of the superficially normal B and A stars {alpha} Dra (A0 III), {tau} Her (B5 IV), {gamma} Lyr (B9 III), and HR 7926 (B8 II-III) are performed consistent with previous studies of this series using spectrograms obtained with Reticon and CCD detectors. Comparisons of the first two analysis with those of the same stars performed earlier in this series which used mostly coadded photographic plates show the general consistency of the derived elemental abundances. A slight increase in the adopted effective temperature produces a corresponding increase in the derived abundances. In these stars the He/H ratios are found to be close to solar. Except for {gamma} Lyr the metals show for the most part marginally subsolar abundance values. But this star has Al, Ca, Sc, and Sr abundances that are substantially underabundant as well as other underabundant values.2001A&A...371.1078Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/371/1078CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/107/353 : CP stars (Lopez-Garcia+, 1994)J/A+AS/125/219 : mu Lep, 7 Sex, HR 4817 & 28 Her abundances (Adelman+ 1997)J/A+AS/129/563 : Abundances of HR 4487, 14 Hyd and 3 Cen A (Pintado+ 1998)J/A+AS/137/227 : HD 133029 & HD 192913 abundances (Lopez-Garcia+ 1999)J/MNRAS/316/514 : 28 And + 99 Her elemental abundances (Adelman+, 2000)J/A+A/367/597 : ups Her, phi Her + HR 7018 abundances (Adelman+, 2001)J/A+A/371/1078 : alpha Dra, tau Her, gamma Lyr, HR 7926 (Adelman+, 2001)J/A+A/394/187 : {gamma} Ser & 101 Her elemental abundances (Caliskan+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/371/1078https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/371/1078http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/371/1078https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/371/1078https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/371/1078http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/371/1078GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/371/1078/table5aElemental abundancesrecnoRecord number assigned by the VizieR team.
