The star formation rates (SFRs) and metallicities of a sample of 294 galaxies with visually classified, strong, large-scale bars are compared to a control sample of unbarred disc galaxies selected from the Sloan Digital Sky Survey Data Release 4. The fibre (inner few kpc) metallicities of barred galaxies are uniformly higher (at a given mass) than the unbarred sample by ∼0.06 dex. However, the fibre SFRs of the visually classified barred galaxies are higher by about 60 per cent only in the galaxies with total stellar mass M★ > 1010 M⊙. The metal enhancement at M★ 1010 M⊙. However, due to the much lower fraction of pairs than bars, bars account for ∼3.5 times more triggered central star formation than interactions.

The solar vicinity (2012, methodology): “…chemical model we used was not motivated by the effect of the bar and is, in fact, a somewhat extreme case regarding the strong increase in [Fe/H] at r < 5 kpc, this choice may well be the correct one, considering the stronger chemical enrichment expected inside bars (e.g., Ellison et al. 2011).”
