The Calibration of the O/h Abundance Indicators for Extragalactic H Ii Regions Based on O Ii Recombination Lines

Abstract

Based on O II recombination lines we present a new calibration (called O IIRL) of Pagel’s O23 indicator to determine the O/H abundance ratio in extragalactic H II regions and emission line galaxies. The O IIRL calibration produces O/H abundances about a factor of two higher than those derived from the T (4363) method with t = 0.00. The O IIRL calibration… (More)
