ELECTROSTATIC CONFIGURATIONS CROSSOVER NEUTRON STAR CORE

摘要

Suppose that neutron star core be composed by degenerate neutrons, protons and electrons above nuclear density. Applying theWeizsacker mass formula for the nuclear potential energy of neutron star cores, we integrate Einstein-Maxwell equation with electro and β- equilibrium to obtain the radial distributions of baryon and electron densities in the global neutrality condition. It is shown that at nuclear density baryon densities sharply go to zero in a few fermi, while the electron density well extends to a few hundred Compton lengths, as results a strong electric field is developed in the core surface-shell of thickness of a few fermi.
