Incompressibility and symmetry energy of a neutron star
نویسندگان
چکیده
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 acquired by polynomial fitting saturation curves three different mean-field parameter sets (NL3, G3, IU-FSU). modified folded with star's density-dependent weight function calculate numerical values incompressibility NL3 set, being stiffest equation state, has higher all compared other two sets.

Symmetry energy , neutron star crust and neutron skin thickness ⋆
We analyze the correlations of the slope and curvature parameters of the symmetry energy with the neutron skin thickness of neutron-rich isotopes, and the crust-core transition density in neutron stars. The results are obtained within the microscopic Brueckner–Hartree–Fock approach, and are compared with those obtained with several Skyrme and relativistic mean field models.
متن کاملSymmetry energy at subnuclear densities and nuclei in a neutron-star crust
We examine how the properties of inhomogeneous nuclear matter at subnuclear densities depend on the density dependence of the symmetry energy. We focus on a parameter that characterizes the density dependence of the symmetry energy S(n) at about nuclear density n0. It is the density symmetry coefficient L = 3n0(dS/dn)n=n0 . From the saturation properties of stable nuclei, we find that the usual...
متن کاملIncompressibility of neutron - rich matter
The saturation properties of neutron-rich matter are investigated in a relativistic mean-field formalism using two accurately calibrated models: NL3 and FSUGold. The saturation properties—density, binding energy per nucleon, and incompressibility coefficient—are calculated as a function of the neutron-proton asymmetry α ≡ (N − Z)/A to all orders in α. Good agreement (at the 10% level or better)...

متن کاملConstraints on the symmetry energy from neutron star equation of state
We develop an equation of state (EOS) for neutron star (NS) matter, which forbids the direct URCA cooling and satis es the recent information on the mass and the radius, simultaneously. At sub-saturation densities, the symmetry energy of the EOS is well described by a function Esym ( ) = 31:6 ( = 0) with 0:70 0:77. This constraint on the density dependence of the symmetry energy is much severer...
