cds-question@unistra.frvariable-starschemically-peculiar-starsspectroscopyWe present chemical abundances in the photosphere of delta Scuti (delta Sct) - a prototype of the class of pulsating variables - determined from the analysis of a spectrum obtained by using the 2-m telescope at the Peak Terskol Observatory and a high-resolution spectrometer with R=52000, a signal-to-noise ratio 250 and from International Ultraviolet Explorer spectra. The abundance pattern of delta Sct consists of 49 chemical elements. The abundances of 19 elements have not been investigated previously. The abundances of Pr and Nd obtained from the lines of the second and third spectra are equal. The abundances of heavy elements indicate the overabundances with respect to the solar system values up to 1dex. The abundance pattern of delta Sct is similar to the abundance patterns of Am-Fm or delta Del type stars. A splitting of the cores of all clean lines is observed for the spectra of Sct and HD 57749. This can signify evidence of non-radial pulsations in these stars2005MNRAS.359..865Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/359/865CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/110 : Final Merged Log of IUE Observations (NASA-ESA, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/359/865https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/359/865http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/359/865https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/359/865https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/359/865http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/359/865GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/359/865/table3Iron lines in the Sct 2-m telescope of Peak Terskol Observatory spectrum of delta SctrecnoRecord number assigned by the VizieR team.
