The effect of the energy functional on the pasta-phase properties of catalysed neutron stars

Nuclear pasta, that is an inhomogeneous distribution of nuclear matter characterised by non-spherical clustered structures, expected to occur in a narrow spatial region at the bottom inner crust neutron stars, but width pasta layer strongly model dependent. In framework compressible liquid-drop model, we use Bayesian inference analyse constraints on sub-saturation energy functional and surface tension imposed both ab-initio chiral perturbation theory calculations experimental measurements masses. The posterior models are used obtain general predictions for crust-pasta pasta-core transition with controlled uncertainties. A correlation study allows extracting most influential parameters calculation phases. important role high-order empirical underlined.
