The study about the revised R23-P method for metallicity estimates based on ~20,000 SDSS galaxies

S. Y. Yin, Y. C. Liang, B. Zhang

We select ~20000 metal-rich star-forming galaxies from the SDSS-DR2 to study the R23-P method suggested by Pilyugin et al. for metallicity estimates. The oxygen abundances derived…
