Mass fractions of heavy elements in the convective thermal pulse, just before (dotted lines) and after (solid lines) the main proton ingestion for our 1 M_⊙, [Fe/H] = −2.5 models. Left panel: Non-rotating model (black) and models with v_ini = 30 km s⁻¹ and C_T = 0 (magenta), 1 (green), 50 (red), and 216 (blue). Right panel: Non-rotating model (black) and models with v_ini = 90 km s⁻¹ and C_T = 50 (red) and 216 (blue).
