Left panel a) range of energies per baryon (defined by e = ℰ/n − m_nc² where m_n is the neutron mass) of nucleonic matter in beta equilibrium at zero temperature as a function of the baryon density for the unified Brussels-Montreal EoSs (Goriely et al. 2010). The shaded area reflects the different degrees of stiffness of these EoSs: the lower limit corresponds to BSk19, the upper to BSk21. Right panel b) corresponding range of pressures.
