cds-question@unistra.frhorizontal-branch-starsvisible-astronomysloan-photometryinfrared-photometryWe discuss a 175{deg}2 spectroscopic survey for blue horizontal branch (BHB) stars in the Galactic halo. We use the Two Micron All Sky Survey (2MASS, <II/246>) and the Sloan Digital Sky Survey (SDSS) to select BHB candidates, and we find that the 2MASS and SDSS color selection is 38% and 50% efficient, respectively, for BHB stars. Our samples include one likely runaway B7 star 6kpc below the Galactic plane.2005AJ....130.1097Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/1097CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.sdss.org : The Sloan Digital Sky Survey home pageII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/126/1362 : Century Survey Galactic Halo Project.
