Contribution of individual electron captures to the neutronization close to the centre as a function of the mass coordinate for a Chandrasekhar-mass model with (a) ρc = 2 × 109 g cm−3(model C2), (b) ρc = 3 × 109 g cm−3(model C3), (c) ρc = 4 × 109 g cm−3(model C4), and (d) ρc = 5 × 109 g cm−3(model C5). In panel c, the curves are labelled with the species name. In all panels, the contribution from protons has been scaled down by a factor ten.
