Effects of the symmetry energy slope on the exotic content of the neutron stars

Abstract

By varying the symmetry energy slope (L), I investigate how the exotic content within the interiors of neutron stars changes and how it affects both macroscopic and microscopic quantities. Using two different parametrizations (L3\(\omega \rho \) and BigApple), and three different possibilities about the neutron star core (nucleons + hyperons, nucleons+deltas, nucleons + hyperons + deltas), I show that, for the models analyzed in this work, changing the slope barely changes the amount of hyperons, but it can strongly suppress the \(\Delta \) resonances for large values of L. I also show that, in general, the presence of exotic content will be more evident for lower values of L than for large ones. Differences and similarities between the two parametrizations are also analyzed.
