The Mean

The global mass dependence of the nuclear symmetry energy asym(A) and its two basic ingredients due to the mean-level spacing ε(A) and effective strength of the isovector mean-potential κ(A) is studied within the Skyrme-Hartree-Fock model. In particular, our study determines the ratio of the surface-to-volume contributions to asym(A) to be rS/V~1.6 and reveals that after removing momentum-dependent effects by rescaling ε and κ with isoscalar and isovector effective masses, respectively, one obtains ε⋆ ≈ κ⋆.

Potential Part

We construct a class of nuclear equations of state based on a schematic potential model, that originates from the work of Prakash et. al. [1], which reproduce the results of most microscopic calculations. The equations of state are used as input for solving the Tolman- Oppenheimer-Volkov equations for corresponding neutron stars. The potential part contribution of the symmetry energy to the total energy is parameterized in a generalized form both for low and high values of the baryon density. The obtained nuclear equations of state are applied for the systematic study of the global properties of a neutron star (masses, radii and composition). We also address on the problem of the existence of correlation between the pressure near the saturation density and the radius.
