cds-question@unistra.frcarbon-starsvisible-astronomysloan-photometryinfrared-photometryWe report the discovery of 39 faint high-latitude carbon stars (FHLCs) from Sloan Digital Sky Survey (SDSS) commissioning data. The objects, each selected photometrically and verified spectroscopically, range over 16.6<r*<20.0 and show a diversity of temperatures as judged by both colors and NaD line strengths. Although a handful of these stars were previously known, these objects are, in general, too faint and too warm to be effectively identified in other modern surveys such as the Two Micron All Sky Survey, nor are their red/near-IR colors particularly distinctive. We present proper-motion measures for each object, indicating that the sample is a mixture of extremely distant (greater than 100kpc) halo giant stars, useful for constraining halo dynamics, and members of the recently recognized exotic class of very nearby dwarf carbon (dC) stars.2002AJ....124.1651Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/124/1651CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : The 2MASS database (IPAC/UMass, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/124/1651https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/124/1651http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/124/1651https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/124/1651https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/124/1651http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/124/1651GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/124/1651/table1 (Faint high-latitude carbon stars discovered in SDSS commissioning data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/124/1651/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/124/1651/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/124/1651/table1?GETtext/xml+votable180.050000true7.554583-0.5408330.005555555555555556Cone search capability for table J/AJ/124/1651/table2 (SDSS faint high-latitude carbon stars in released 2MASS fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/124/1651/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/124/1651/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/124/1651/table2?GETtext/xml+votable180.050000true7.554583-0.5408330.0055555555555555566/4098 6391 6540 6558 6608 6612 7456 10099 10183 10200 17767 17807 18005 18013 18072 18176 18844 19036 19038 19748 19751 23190 25587 25938 25944 25960 25999 26264 26368 26972 26983 26988 26993 27246 27250 31314 31383 36802 409598.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/124/1651?format=asciiOpticalInfrareddefaultJ/AJ/124/1651/table1Faint high-latitude carbon stars discovered in SDSS commissioning datarecnoRecord number assigned by the VizieR team.
