Results of the CO test. Top left: evolution of the nuclear energy rate as a function of the temperature obtained with net14, net90-noec, and WinNet-noec. Top) right: same, but including e⁻ captures. Letters A, B, C, and D refer to normal combustion, relaxation to NSE, full NSE, and adiabatic expansion, respectively. Bottom left: evolution of the mean molecular weight μ_i of ions as a function of temperature obtained with net14, net90-noec and WinNet-noec. Bottom right: same, but including e⁻ captures.
