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 $$\\omega \\rho $$ ω ρ 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 $$\\Delta $$ Δ 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.
