A Photometric System for Metallicity Mapping in Galaxies
arXiv:astro-ph/9906353 · doi:10.1023/A:1017585409743
Abstract
A new photometric system suitable for deep, precise and quick metallicity mapping in galaxies is proposed. We find a linear correlation between our metallicity index and the Mg2 index for stellar, globular cluster, and early-type galaxy spectra, and model spectral energy distributions of the simple stellar populations.
