Schematic figure of [Zn/Fe] as a function of [Fe/H] in the Milky Way (gray) and its dwarf galaxy satellites: Sagittarius (dark green), Sextans (green), Sculptor (blue), Draco (pink), Ursa Minor (orange) and Carina (yellow). Lines show mean trends, while scatter is indicated by shaded areas, and notable outliers are identified by individual squares. The two branches at [Fe/H] ≳−0.5 in the Milky Way represent the mean trends as measured by dwarf stars (higher values) and giant stars (lower values). References: Dwarf galaxies: see Table 1.
