cds-question@unistra.frspectroscopic-binary-starssubdwarf-starsstellar-atmospheresWe present the analysis of a high-resolution, high-quality sample of optical spectra for 76 subdwarf B (sdB) stars from the ESO Supernova Ia Progenitor Survey (SPY, Napiwotzki et al., 2001A&A...367..973N). Effective temperature, surface gravity, and photospheric helium abundance are determined simultaneously by fitting the profiles of hydrogen and helium lines using synthetic spectra calculated from LTE and NLTE model atmospheres. We perform a detailed comparison of our measurements with theoretical calculations, both for single star evolution and for binary population synthesis models of close binary evolution.2005A&A...430..223Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/430/223CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/442/1023 : 17 bright subdwarf B stars radial velocity (Edelmann+, 2005)J/ApJ/613/200 : Hubble Higher z Supernova Search, HHZSS (Strolger+, 2004)III/235 : Spectroscopically Identified White Dwarfs (McCook+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/430/223https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/430/223http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/430/223https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/430/223https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/430/223http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/430/223GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/430/223/table1 (Results of our spectral analysis.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/430/223/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/430/223/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/430/223/table1?GETtext/xml+votable180.050000true122.803208310.95466670.0055555555555555566/255 4610 8278 12334 12404 12430 12627 12673 16501 16529 16551 16629 16672 16744 16769 17186 17526 17815 18098 18451 18601 18706 18738 18863 18997 19045 19057 19741 20224 20236 21040 24700 25041 25450 25566 25576 25735 25905 26007 26748 26837 26872 27177 31337 31468 32307 33508 34101 34127 34796 34958 35150 35251 35640 35713 35767 35769 35781 36720 36831 38875-38876 44217 44652 44721 44789 44915 44948 45026-45027 45046 46387 46714 46795 46859https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/430/223?format=asciiOpticaldefaultJ/A+A/430/223/table1Results of our spectral analysis.recnoRecord number assigned by the VizieR team.
