Abstract

In a unified treatment we extrapolate results for neutral atoms with heavy nuclei to nuclear matter cores of stellar dimensions with mass numbers A ≈ (m_Planck/m_n)³ ~ 10⁵⁷. We give explicit analytic solutions for the relativistic Thomas–Fermi equation of N_n neutrons, N_p protons and N_e electrons in beta equilibrium, fulfilling global charge neutrality, with N_p = N_e. We give explicit expressions for the physical parameters including the Coulomb and the surface energies and we study as well the stability of such configurations. Analogous to heavy nuclei these macroscopic cores exhibit an overcritical electric field near their surface.
