Equilibrium abundances (dashed lines) of the ⁸B nuclides and the cumulative neutrino flux from their disintegration, ϕ_⁸B (solid lines), along the radial coordinate r. They are presented as a function of the temperature, for three SSMs with different chemical mixtures, as given in the legend. Abundances are in mole per gram, and the flux, as usual, is computed for an observer at 1 AU.
