Fluxes f during the main proton ingestion event, at the bottom of the convective pulse, when the neutron density is maximal (red point in the top panel of Fig. 2). The fluxes are defined as f = N_avρY_iY_j⟨σv⟩ (where Y_i and Y_j are the molar mass fractions of the target and projectile, respectively, N_av the Avogadro number and ⟨σv⟩ the nuclear reaction rate). The colors of the arrow identify various reaction fluxes. The isotopes mass fractions are color-coded according to the right sidebar. The black squares denote stable isotopes.
