cds-question@unistra.frhorizontal-branch-starsstellar-atmospheresline-intensitiesWe have conducted spectrum analyses of 24 field metal-poor ([Fe/H]<-2) red horizontal-branch (RHB) stars identified in the HK objective-prism survey and 6 such stars in the globular cluster M15, based on high-quality spectra (R~40000, S/N~100) obtained with the Magellan Inamori Kyocera Echelle spectrograph at the Clay 6.5m telescope at Las Campanas Observatory. The atmospheric parameters of the RHB stars provide interesting bridges between turnoff stars of similar temperature and red giant branch (RGB) stars of similar gravity, and they permit investigations of abundance trends [X/Fe] versus [Fe/H] in a relatively unexplored region of the temperature-gravity plane. We find that the Teff, logg, vt, and [Fe/H] values determined from our spectra are consistent with expectations from literature spectroscopic studies of other evolved metal-poor stellar classes.2006AJ....132...85Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/132/85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/380/578 : EW of 13 horizontal branch stars (Tautvaisiene+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/132/85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/132/85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/132/85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/132/85https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/132/85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/132/85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/132/85/stars (Star positions (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/85/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/85/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/85/stars?GETtext/xml+votable180.050000true65.79375-30.6177780.0055555555555555566/8367 12405 16462 18580 31608 33596 33708 34232 34600 34708 36295 45801 45868 45881 46080 46462 46580 46691 46705 46751 46851 47217 48145 48160 48162 48363 48544 48591https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/132/85?format=asciiOpticaldefaultJ/AJ/132/85/starsStar positions (from Simbad)recnoRecord number assigned by the VizieR team.
