General relativistic treatment of f -mode oscillations of hyperonic stars

Systematic analysis of the impacts of symmetry energy parameters on neutron star properties

“…This implies that the correlations of NS properties with individuals symmetry energy parameters are masked in the absence of appropriate constraints on the EoSs at low densities. It also partly explains why the outcome of the similar correlations studied in the earlier publications [31,34,36,39,45] are at variance. These correlations improve a little bit with the increase in the transition density.…”

“…The correlations of NS properties with various symmetry energy parameters and the pressure of β−equilibrated matter have been extensively investigated earlier using non-parametric [81], parametric [31,82], and physics-based models [34,36,38,39,81] and found to yield the results which are sometimes at variance, as summarized in Table III of Ref. [45].…”

“…1. Often, U-Unc and G-Unc distributions have been employed to study the correlations of Λ 1.4 with various symmetry energy parameters [31,34,36,39].…”

“…Our results for the correlations for the U-Unc case are qualitatively similar to those obtained in Refs. [34,39] with a similar strategy for nuclear matter parameters but with different models. Similar qualitative trends are observed for the G-Unc [31].…”

“…There have been several attempts to study the correlations of radius and tidal deformability of a neutron star with various nuclear matter parameters which determine the density-dependence of symmetry energy [13,30,31,[33][34][35][36][37][38][39][40][41][42][43]. The nuclear matter parameters employed for the investigations are often drawn randomly from uniform or Gaussian distributions assuming each of the parameters to be uncorrelated and independent of each others.…”
