Alpha-bimodality forms naturally in a simulated disc galaxy via early high star formation, minor-merger corona dilution, and subsequent accreted gas flows without major mergers or radial migration.
In addition, we select only stars with 3500<T eff[K]<6500 and 1<logg[dex]<3.5

Portrait of a Galaxy on FIRE: Is the $\alpha$-bimodality a natural consequence of inside-out disc growth in a hierarchical formation scenario?
