cds-question@unistra.frchemical-abundancesline-intensitiesNew spectroscopic observations are presented for a sample of thirty-one blue horizontal branch (BHB) star candidates that are sufficiently nearby to have reliable proper motions. Comments are given on a further twenty-five stars that have previously been suggested as BHB star candidates but which were not included in our sample. Moderately high-resolution spectra ({lambda}/{Delta}{lambda}=~15000) of twenty five of our program stars were taken with the coude feed spectrograph at Kitt Peak. Twelve of the program stars were also observed with the CAT spectrograph at ESO. Six of these program stars were observed from both hemispheres. IUE low-resolution spectra are available for most of our candidates and were used, in addition to other methods, in the determination of their T_eff_ and reddening. Abundances were obtained from these spectra using models computed by Castelli with an updated version of the ATLAS9 code (Kurucz, 1993, CD-ROM No. 13). All thirty one candidates are halo stars.2000A&A...364..102Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/364/102CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/108/1722 : Blue horizontal branch stars (Kinman+ 1994)J/A+AS/109/171 : Blue horizontal branch stars catalog (Flynn+, 1995)J/A+A/347/69 : Abundances of halo early-type stars (Rolleston+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/364/102https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/364/102http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/364/102https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/364/102https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/364/102http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/364/102GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/364/102/stars (Star positions and magnitudes (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/364/102/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/364/102/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/364/102/stars?GETtext/xml+votable180.050000true197.35666724.3236110.0055555555555555566/2248 2966 4322 4373 5287 7436 8332 10282 10811 10904 15097 17955 21928 24351 25601 27512 28575 32558 34189 35096 35151 37117 41967 42553 43693 44213 46335 48108 48194https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/364/102?format=asciiOpticaldefaultJ/A+A/364/102/starsStar positions and magnitudes (from Simbad)NameObject namemeta.id;meta.maincharprimaryrecnoRecord number assigned by the VizieR team.
