cds-question@unistra.frearly-type-starsb-starschemical-abundancesspectroscopyultraviolet-astronomyWe derived the stellar parameters (angular diameters, effective temperatures, metallicities) and interstellar reddenings for 20 Slowly Pulsating B (SPB) and 34 reference stars observed during the IUE satellite mission. The parameters were derived by means of an algorithmic procedure of fitting theoretical flux distributions to the low-resolution IUE spectra and optical spectrophotometric observations. Since the metallicity [m/H] has a special importance for pulsating B type stars, we focused our attention on that parameter. We found that the mean value of the metallicity of the considered SPB and reference stars amounts to [m/H]~-0.20. The results only slightly depend on the reduction procedure used for the IUE images (NEWSIPS and INES). The metal abundances obtained in this paper are in accordance with the average value of -0.2dex for stars in the solar neighborhood recently reported by other investigators.2003A&A...404..689Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/404/689CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVI/99 : Merged Log of IUE Observations (NASA-ESA, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/404/689https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/404/689http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/404/689https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/404/689https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/404/689http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/404/689GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/404/689/stars (Star positions and magnitudes (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/404/689/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/404/689/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/404/689/stars?GETtext/xml+votable180.050000true6.06541752.020.0055555555555555566/463 496 1430 1766 1770 1826 2976 3024 3136 3144 4473 9680 9847 10731 12766 14381 14541 15782 21099 21433 21879 22863 22885 22958 23115 23255 23493 27574 29014 29040 29711 32513 33888 35095 36220 36651 37584 37639 37790 38216 39310 41516 43117 43224 43383 43531 44043 44822 44903 45132 46615 47703https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/404/689?format=asciiUVdefaultJ/A+A/404/689/starsStar positions and magnitudes (from Simbad)HDHD numbermeta.id;meta.mainintprimaryrecnoRecord number assigned by the VizieR team.
