The Interplay of Symmetry Energy Uncertainties, Nonlinear $\sigma -\delta$ Coupling, and Dark Matter in Neutron Star Macroscopic Properties

Zhaohui Feng, Xiaoxuan Zhai, Shuangxuan Chen +1

The poorly constrained density dependence of the nuclear symmetry energy introduces significant uncertainties in the equation of state (EOS) of dense nuclear matter and, consequent…
