Oxygen abundances in the most oxygen-rich spiral galaxies.

PILYUGIN L.S., THUAN T.X. and VILCHEZ J.M.

Abstract (from CDS):

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 HII 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 of ≳5) than the previously accepted value. The central oxygen abundance in the Milky Way is similar to that in other large spirals.
