cds-question@unistra.frmagellanic-cloudsemission-line-starsspectroscopyphotometryWe present new, accurate positions, spectral classifications, radial and rotational velocities, H{alpha} fluxes, equivalent widths and B, V, I, R magnitudes for 579 hot emission-line stars (classes B0-F9) in the Large Magellanic Cloud (LMC) which include 469 new discoveries. Candidate emission-line stars were discovered using a deep, high-resolution H{alpha} map of the central 25 degree^2^ of the LMC obtained by median stacking a dozen 2h H{alpha} exposures taken with the UK Schmidt Telescope (UKST). Spectroscopic follow-up observations on the Anglo-Australian Telescope, the UKST, the Very Large Telescope, the South African Astronomical Observatory 1.9m and the 2.3-m telescope at Siding Spring Observatory have established the identity of these faint sources down to magnitude R_equiv_~23 for H{alpha} (4.5x10^-17^ergs/cm^2^/s/{AA}).2012MNRAS.425..355Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/425/355CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/252 : The USNO-A2.0 Catalogue (Monet+ 1998)I/271 : The Guide Star Catalog, Version 2.2 (GSC2.2) (STScI, 2001)J/AcA/50/307 : OGLE LMC BVI photometry (Udalski+, 2000)J/MNRAS/405/1349 : LMC PNe [OIII] 5007{AA} and H{beta} flux (Reid+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/425/355https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/425/355http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/425/355https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/425/355https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/425/355http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/425/355GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/425/355/catalog (Catalogue of hot emission-line stars in the LMC UKST H{alpha} survey (tables A2 and A1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/425/355/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/425/355/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/425/355/catalog?GETtext/xml+votable180.050000true73.230875-69.16730560.0055555555555555565/8263 8269 8273-8276 8280 6/33047 33051 33073 33090-33091 33110 33112-33114 33124-33126https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/425/355?format=asciiOpticaldefaultJ/MNRAS/425/355/catalogCatalogue of hot emission-line stars in the LMC UKST H{alpha} survey (tables A2 and A1)BmagO?
