EOSs of β-stable neutrino-free matter at different temperature values of T = 0, 2, 5, 10, and 20 MeV. In the left panel, we use a cold crust assuming the transition between the cold crust and the uniform core fixed at n = 0.08 fm⁻³. In the right panel, we use a hot inner crust and the crust–uniform matter transition is determined as described in Sect. 3, consistently with Fig. 1.
