LAUSR

In this work, we study the effects of nuclear symmetry energy slope on neutron star dense matter equation of state and its impact on neutron star observables (mass-radius, tidal response). We construct the equation of state within the framework of covariant density functional theory implementing coupling schemes of non-linear and density-dependent models with viability of heavier non-nucleonic degrees of freedom. The slope of symmetry energy parameter (Lsym) is adjusted following density-dependence of isovector meson coupling to baryons. We find that smaller values of Lsym at saturation favour early appearance of ∆-resonances in comparison to hyperons leading to latter’s threshold at higher matter densities. We also investigate the dependence of Lsym on tidal deformability and compactness parameter of a 1.4 M neutron star for different equation of states and observe similar converging behaviour for larger Lsym values.
