The [NII]/Hα calibration of the metallicity of galaxies from Te-based abundances

Year: 2012

Type: article

Abstract: We gather a sample of both metal-rich and metal-poor galaxies. Both samples have oxygen abundances estimated from electron temperature (Te). The calibration of the emission-line ratio, N2(≡log([NII]6583/Hα), to oxygen abundances is then re-derived from this combined sample, finding good agreement for the wide metallicity and line-ratio ranges considered.
