Oxygen abundances in the most oxygen-rich spiral galaxies


Oxygen abundances in the spiral galaxies expected to be richest in oxygen are estimated. The new abundance determinations are based on the recently discovered ff – relation between auroral and nebular oxygen line fluxes in high-metallicity H ii regions. We find that the maximum gas-phase oxygen abundance in the central regions of spiral galaxies is 12+log(O/H) ∼ 8.75. This value is significantly lower (by a factor
