cds-question@unistra.frmagellanic-cloudssupergiant-starsstellar-spectral-typeseffective-temperaturechemical-abundancesvisible-astronomybroad-band-photometryinfrared-photometryHigh-quality spectra of 90 blue supergiant stars in the Large Magellanic Cloud are analyzed with respect to effective temperature, gravity, metallicity, reddening, extinction, and extinction law. An average metallicity, based on Fe and Mg abundances, relative to the Sun of [Z]=-0.35+/-0.09 dex is obtained. The reddening distribution peaks at E(B-V)=0.08 mag, but significantly larger values are also encountered. A wide distribution of the ratio of extinction to reddening is found ranging from R_V_=2 to 6. The results are used to investigate the blue supergiant relationship between flux-weighted gravity, g_F_=g/T_eff_^4^, and absolute bolometric magnitude M_bol_. The existence of a tight relationship, the Flux-weighted Gravity-Luminosity Relationship (FGLR), is confirmed. However, in contrast to previous work, the observations reveal that the FGLR is divided into two parts with a different slope. For flux-weighted gravities larger than 1.30 dex, the slope is similar to that found in previous work, but the relationship becomes significantly steeper for smaller values of the flux-weighted gravity. A new calibration of the FGLR for extragalactic distance determinations is provided.2017AJ....154..102Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/102CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+AS/24/35 : LMC A-F supergiants (Stock+, 1976)J/A+AS/35/347 : OB and Supergiants stars in LMC (Philip+, 1979)J/AN/320/105 : Spectrophotometry of 26 supergiants in the LMCJ/A+A/456/623 : VLT-FLAMES survey of massive stars (Evans+, 2006)J/AJ/132/2268 : SAGE calibration stars (Meixner+, 2006)J/A+A/575/A70 : VLT-FLAMES Tarantula Survey: B supergiants (McEvoy+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/154/102https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/154/102http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/154/102https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/154/102https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/154/102http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/154/102GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/154/102/BA (LMC BA supergiants results (MagE) (tables 1 and 6))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/102/BA?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/102/BA?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/102/BA?GETtext/xml+votable180.050000true82.6671083333-67.27721388890.005555555555555556Cone search capability for table J/AJ/154/102/Photometry (LMC supergiants optical photometry (table 11) , 2MASS photometry (table 12) and IRAC photometry (table 13))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/102/Photometry?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/102/Photometry?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/102/Photometry?GETtext/xml+votable180.050000true73.8872233-66.42441690.005555555555555556Cone search capability for table J/AJ/154/102/OB1 (LMC OB supergiants results (MagE and FLAMES I) (tables 2 and 7))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/102/OB1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/102/OB1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/102/OB1?GETtext/xml+votable180.050000true73.8872125-66.42441666670.005555555555555556Cone search capability for table J/AJ/154/102/OB2 (LMC OB supergiants results (FEROS) (tables 3 and 8))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/102/OB2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/102/OB2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/102/OB2?GETtext/xml+votable180.050000true73.3751208333-66.92451111110.005555555555555556Cone search capability for table J/AJ/154/102/OB3 (LMC VFTS OB supergiants results (tables 4 and 9))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/102/OB3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/102/OB3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/102/OB3?GETtext/xml+votable180.050000true84.229875-69.19380555560.0055555555555555566/33051 33053 33054 33076 33078 33079 33091 33092 33094 33095 33097 33098 33100 33101 33103 33104 33106 33107 33112 33113 33116 33120 33121 33123 33124 33126 331282.0616683193919197e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/154/102?format=asciiOpticalInfrareddefaultJ/AJ/154/102/BALMC BA supergiants results (MagE) (tables 1 and 6)E_RV[0.19/2.37] Upper limit uncertainty in RVstat.error;stat.maxfloatrecnoRecord number assigned by the VizieR team.
