Red giants in the Small Magellanic Cloud - II. Metallicity gradient and age-metallicity relation

Dobbie, Paul; Cole, Andrew; Subramaniam, Annapurni; Keller, Stefan

Description

We present results from the largest Ca II triplet line metallicity study of Small Magellanic Cloud (SMC) field red giant stars to date, involving 3037 objects spread across approximately 37.5 deg2, centred on this galaxy. We find a median metallicity of [Fe/H] = -0.99 ± 0.01, with clear evidence for an abundance gradient of -0.075 ± 0.011 dex deg-1 over the inner 5°. We interpret the abundance gradient to be the result of an increasing fraction of young stars with decreasing galactocentric...[Show more]
