cds-question@unistra.frspectrophotometryLow-resolution spectra (~5A) for 40 red supergiants in the Small Magellanic Cloud were compared with synthetic spectra, and their metallicities were derived. A mean metallicity of [Fe/He]=-0.71 is found for 38 stars cooler than T_eff_<4500K. Using the stellar parameters derived, the carbon abundances were determined by comparing synthetic spectra at the G-band region to the observed spectra. A mean {epsilon}(C)=7.85 is found, clearly higher than the low values suggested in the literature for the H II regions.1995A&A...304..347Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/304/347CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/304/347https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/304/347http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/304/347https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/304/347https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/304/347http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/304/347GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/304/347/stars (List of programme stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/304/347/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/304/347/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/304/347/stars?GETtext/xml+votable180.050000true9.345228-73.4291770.0055555555555555566/33294-33295 33304 33306 33316-33317 33319 33328https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/304/347?format=asciiOpticaldefaultJ/A+A/304/347/starsList of programme starsrecnoRecord number assigned by the VizieR team.
