Metallicities and carbon abundances of 40 field red supergiants in the Small Magellanic Cloud.
MELIANI M.T., BARBUY B. and RICHTLER T.
Abstract (from CDS):
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.
