The influence of asymmetry on a magnetized proto-neutron star

Abstract

Using the Relativistic Mean Field Theory (RMF) it is shown that different proton fraction which is directly connected with the neutron excess and with the asymmetry of the system affects proto-neutron stars parameters and changes their composition. The obtained form of the equation of state allows to construct the mass-radius relations and shows that the increasing asymmetry creates more compact stars. The inclusion of delta meson together with nonlinear vector meson interaction terms and magnetic field make this effect even stronger.
