TL;DRAbstract

The recently formulation of the relativistic Thomas-Fermi model for compressed atoms is applied to the study of white-dwarf equilibrium configurations in the framework of general relativity. The equation of state is obtained as a function of the compression by considering each atom constrained in a Wigner-Seitz cell and it takes into account the beta equilibrium and the Coulomb interaction between the nuclei and the surrounding electrons. The consequences on the numerical value of the Chandrasekhar-Landau mass limit are presented as well as the modifications to the mass-radius relation for 4 He and 56 Fe white-dwarf equilibrium configurations.
