Nucleosynthetic fluxes from ¹⁶O to ¹²C due to the ¹⁶O(p,α)¹³N (solid lines) and the ¹⁶O(γ, α)¹²C (dot-dashed lines) reactions as a function of time, in a mass shell with peak temperature 4 × 10⁹ K, for a 1.06 M_⊙ WD with either progenitor metallicity Z = 2.25 × 10⁻⁴ (red) or Z = 0.0225 (blue). The nucleosynthetic flux of the ¹²C fusion reaction is also plotted with dotted lines.
