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

Figure 2

The binding energies of (𝑛,𝑝,𝑒) and (𝑛,𝑝,Λ,𝑒). The onset density of Λ is about 𝑘_𝐹=1.7 fm⁻¹ as shown in the figure. The ratios of Λ-coupling constant on 𝜎 are (dotted line) 𝑟^𝜎_Λ𝑁=𝑔_𝜎Λ/𝑔_𝜎𝑁=1.0, and (dashed line) 𝑟^𝜎_Λ𝑁=2/3, (dotted-dashed line) 𝑟^𝜎_Λ𝑁=1/3, respectively. The other coupling constants are fixed as in Table 1.
