The Density-Dependent Correlations among Observables in Nuclear Matter and Hyperon-Rich Neutron Stars

Table 1

Properties of nuclear matter and (𝑛,𝑝,Σ⁻,𝑒), (𝑛,𝑝,Λ,𝑒) neutron stars. The properties of symmetric nuclear matter connected with isospin-asymmetric, beta-equilibrium matter (𝑛,𝑝,𝑒) whose EOS produces 𝑀_max(𝑛,𝑝,𝑒)=2.50𝑀_⊙ are listed. The coupling constants are chosen from the data NHA^2.50 in the paper [20, 21].
