Figure 35: Variation of the adiabatic index γ of supernova matter with mass density ρ for three different EoSs with trapped neutrinos: Lattimer and Swesty [255] (compressible liquid drop model), Shen [374375] (relativistic mean field theory in the local density approximation) and Wolff [197] (Hartree–Fock with Skyrme nucleon-nucleon interaction). The lepton fraction is Y = 0.4 L and the entropy per nucleon is equal to 1kB.
