cds-question@unistra.frgalaxiesinfrared-photometryvisible-astronomybroad-band-photometrystellar-spectral-typesWe describe our spectroscopic follow-up to the Local Group Galaxy Survey (LGGS) photometry of M31 and M33. We have obtained new spectroscopy of 1895 stars, allowing us to classify 1496 of them for the first time. Our study has identified many foreground stars, and established membership for hundreds of early- and mid-type supergiants. We have also found nine new candidate luminous blue variables and a previously unrecognized Wolf-Rayet star. We republish the LGGS M31 and M33 catalogs with improved coordinates, and including spectroscopy from the literature and our new results. The spectroscopy in this paper is responsible for the vast majority of the stellar classifications in these two nearby spiral neighbors. The most luminous (and hence massive) of the stars in our sample are early-type B supergiants, as expected; the more massive O stars are more rare and fainter visually, and thus mostly remain unobserved so far. The majority of the unevolved stars in our sample are in the 20-40M_{Sun}_ range.2016AJ....152...62Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/152/62CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/759/11 : Wolf-Rayet content of M31 (Neugent+, 2012)J/ApJ/750/97 : The yellow and red supergiants of M33 (Drout+, 2012)J/ApJ/733/123 : The Wolf-Rayet content of M33 (NGC 598) (Neugent+, 2011)J/ApJ/703/441 : Yellow supergiants in M31 (Drout+, 2009)J/ApJ/703/420 : Red supergiants in M31 (Massey+, 2009)J/AJ/134/2474 : H{alpha} emission-line stars in 7 galaxies (Massey+, 2007)J/AJ/133/2393 : UBVRI phot. in 7 Local Group dwarfs galaxies (Massey+, 2007)J/AJ/131/2478 : M31 and M33 UBVRI photometry (Massey+, 2006)J/ApJ/505/793 : New WR star in M33 (Massey+, 1998)J/ApJ/501/153 : VRB photometry of red supergiants (Massey 1998)J/ApJ/469/629 : UV-brightest stars of M33 and its nucleus (Massey+ 1996)J/AJ/110/2715 : UBV photometry in NGC 6822, M31 and M33 (Massey+ 1995)J/AJ/96/1884 : BVRJHK photometry of M31 red supergiants (Humphreys+ 1988)http://tdc-www.harvard.edu/ : SAO Telescope Data Centerhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/152/62https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/152/62http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/152/62https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/152/62https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/152/62http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/152/62GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/152/62/catalog (Updated M31 and M33 Local Group Galaxy Survey (LGGS) catalog (tables 5 and 6))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/152/62/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/152/62/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/152/62/catalog?GETtext/xml+votable180.050000true9.257958340.20919440.0055555555555555566/2154 2155 2240 2241 2619 2622 2623 2666 2667 2705 2708 2709 27523.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/152/62?format=asciiInfraredOpticaldefaultJ/AJ/152/62/catalogUpdated M31 and M33 Local Group Galaxy Survey (LGGS) catalog (tables 5 and 6)SpTSpectral typesrc.spTypecharrecnoRecord number assigned by the VizieR team.
