A Correlation between Light Profile and [Mg/Fe] Abundance Ratio in Early-Type Galaxies
We explore possible correlations between light profile shapes, as parameterized by the Sérsic index n or the concentration index Cre(1/3), and relevant stellar population parameters in early-type galaxies. Mean luminosity-weighted ages, metallicities, and abundance ratios were obtained from spectra of very high signal-to-noise ratio and stellar
