Both the incompressibility \Ka of a finite nucleus mass A and that ($K_{\infty}$) infinite nuclear matter are fundamentally important for many critical issues in physics astrophysics. While some consensus has been reached about $K_{\infty}$, accurate theoretical predictions experimental extractions $K_{\tau}$ characterizing isospin dependence have very difficult. We propose differential approac...

We trace a systematic and consistent method to precisely numerate the magnitude range for various structural isospin compositional properties of neutron star. Incompressibility, symmetry energy, slope parameter, curvature star are investigated using relativistic energy density functional within framework coherent fluctuation model. The analytical expression matter is motivated from Br\"uckner a...
