Fraction of formed Pop II (in blue) and Pop III (in green) stars. Each panel corresponds to one halo, with its total luminosity indicated on the upper right side of the panel. The left panel shows our Sextans-like model, h177, with L_V ∼ 3 × 10⁵ L_⊙. The middle panel shows h152 (L_V ∼ 0.5 × 10⁵ L_⊙), representative of medium-mass UFDs. The right panel displays h323, representative of low-mass UFDs (L_V ∼ 0.05 × 10⁵ L_⊙), with quenched star formation after 1 Gyr.
