Abstract
We model gas phase metallicity radial profiles of galaxies in the local
Universe by building on the `bathtub' chemical evolution formalism - where a
galaxy's gas content is determined by the interplay between inflow, star
formation and outflows. In particular, we take into account inside-out disc
growth and add physically-motivated prescriptions for radial gradients in star
formation efficiency (SFE). We fit analytical models against the metallicity
radial profiles of low-redshift star-forming galaxies in the mass range
