cds-question@unistra.frmilky-way-galaxychemically-peculiar-starsradial-velocitychemical-abundancesinfrared-photometryThe chemical abundances of large samples of extremely metal-poor (EMP) stars can be used to investigate metal-free stellar populations, supernovae, and nucleosynthesis as well as the formation and galactic chemical evolution of the Milky Way and its progenitor halos. However, current progress on the study of EMP stars is being limited by their faint apparent magnitudes. The acquisition of high signal-to-noise spectra for faint EMP stars requires a major telescope time commitment, making the construction of large samples of EMP star abundances prohibitively expensive. We have developed a new, efficient selection that uses only public, all-sky APASS optical, 2MASS near-infrared, and WISE mid-infrared photometry to identify bright metal-poor star candidates through their lack of molecular absorption near 4.6 microns.2014ApJ...797...13Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/797/13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/336 : AAVSO Photometric All Sky Survey (APASS) DR9 (Henden+, 2016)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/311 : WISE All-Sky Data Release (Cutri+ 2012)II/328 : AllWISE Data Release (Cutri+ 2013)J/AJ/147/76 : M giant candidate photometry in the MW (Bochanski+, 2014)J/ApJ/762/27 : Most metal-poor stars.
