Mass fraction in neutron stars above a given electron fraction and conditions for an actinde boost. Left panel: mass fractions in neutron stars above the given electron fraction Ye of the x-axis. Rather insensitive to mass and equation of state, the bulk of a neutron star has an electron fraction below ≈0.08, only a tiny mass fraction of ≈10−4 is above this value. Right panel: equilibrium Ye in a neutrino-driven wind as a function of the ratio of (anti)neutrino energies and luminosities (see text for details). Marked is the Ye-range favorable for an actinide boost (0.1−0.15) and the regions expected for neutron star mergers.
