Generalised description of Neutron Star matter with nucleonic Relativistic Density Functional

Understand

In this work, we propose a meta-modelling technique to nuclear matter on the basis of a relativistic density functional with density-dependent couplings.

• Identical density dependence for the couplings both in the isoscalar and isovector sectors is employed.
• We vary the coupling parameters of the model to capture the uncertainties of the empirical nuclear matter parameters at saturation.
• Then, we construct a large ensemble of unified equations of state in a consistent manner both for clusterized and uniform matter in $\beta$-equilibrium at zero temperature.
