cds-question@unistra.frchemically-peculiar-starshalo-starsspectroscopyThe paper presents spectroscopy for 769 hot stars from the HK objective-prism/interference-filter survey of Beers et al. (1985), 193 of which have also available broadband UBV colors. When available, photometric information is used to obtain estimates of the surface temperature for degenerates and for O- and B-type subdwarfs, based on previously derived calibrations. Several extremely hot (T(eff) greater than 50,000 K) He-rich sdO stars are identified. Out of 769 stars in this sample, 551 are clearly identified on the basis of their Balmer line profiles as field horizontal-branch (FHB) or mid-to late-type A stars. The A stars exhibit rotation and line-of-sight dispersion consistent with membership in the galactic thick disk. The FHB stars exhibit kinematic properties which suggest a transition from thick disk to halo.1992AJ....103..267Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/103/267CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/87/1515 : UBV photometry of AB stars in halo (Pier, 1982)J/ApJS/53/791 : Spectroscopy of AB stars in halo (Pier, 1983)J/AJ/90/2089 : Stars of very low metal abundance.
