Descripción
For the first time, a calibration between the He I λ5876/Hβ emission line ratio and the helium abundance y = 12 + log(He/H) for Narrow line regions of Seyfert 2 Active Galactic Nuclei is proposed. In this context, observational data (taken from the SDSS-DR15 and from the literature) and direct abundance estimates (via the Te-method) for a sample of 65 local ( z<0.2 ) Seyfert 2 nuclei are considered. The resulting calibration estimates the y abundance with an average uncertainty of 0.02 dex. Applying our calibration to spectroscopic data containing only strong emission lines, it yields a helium abundance distribution similar to that obtained via the Te-method. Some cautions must be considered to apply our calibration for Seyfert 2 nuclei with high values of electron temperature (≳20000K) or ionization parameter ( logU > −2.0).
