Self-consistent theory of stellar electron capture rates

Recently a novel theory framework has been established for description of electron capture rates at temperatures and densities in stellar environment, based on the relativistic energy density functional. The model includes finite temperature relativistic mean field to determine single-particle basis and the corresponding thermal occupation factors of target nucleus, while relevant charge-exchange excitations are described by the self-consistent finite temperature relativistic random phase approximation (FTRRPA). The calculated electron capture rates for 54, 56Fe are shown in comparison with other advanced theory approaches.
