cds-question@unistra.frgalaxiesemission-line-starsvisible-astronomyh-alpha-photometryWe describe a search for H{alpha} emission-line stars in M31, M33, and seven dwarfs in or near the Local Group (IC 10, NGC 6822, WLM, Sextans B, Sextans A, Pegasus, and the Phoenix dwarf) using interference filter imaging with the KPNO and CTIO 4m telescopes and Mosaic cameras. The survey is aimed primarily at identifying new luminous blue variables (LBVs) from their spectroscopic similarity to known LBVs, avoiding the bias toward photometric variability, which may require centuries to manifest itself if LBVs go through long quiescent periods. Follow-up spectroscopy with WIYN confirms that our survey detected a wealth of stars whose spectra are similar to the known LBVs.2007AJ....134.2474Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/2474CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/131/2478 : M31 and M33 UBVRI photometry (Massey+, 2006)J/AJ/133/2393 : UBVRI phot. in 7 Local Group dwarf galaxies (Massey+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/2474https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/2474http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/2474https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/2474https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/2474http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/2474GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/134/2474/tables (H{alpha} emission-line stars in 8 galaxies (tables 8-15 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/134/2474/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/134/2474/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/134/2474/tables?GETtext/xml+votable180.050000true9.26887539.95013890.0055555555555555566/2154 2155 2240 2241 2619 2622 2623 2666 2667 2705 2708 2709 2752 3042 17165 19990 26858 27351 29716 29718https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/134/2474?format=asciiOpticaldefaultJ/AJ/134/2474/tablesH{alpha} emission-line stars in 8 galaxies (tables 8-15 of the paper)recnoRecord number assigned by the VizieR team.
