J/A+A/304/347  40 field red supergiants in the SMC (Meliani+, 1995)

Metallicities and carbon abundances of 40 field red supergiants in the Small Magellanic Cloud Meliani M.T., Barbuy B., Richtler T. <Astron. Astrophys. 304, 347 (1995)> =1995A&A...304..347M (SIMBAD/NED BibCode)
ADC_Keywords: Spectrophotometry Keywords: Magellanic Clouds - stars: abundances - galaxies: abundances Description: Low-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 Teff<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 ε(C)=7.85 is found, clearly higher than the low values suggested in the literature for the H II regions. File Summary:
