The Vlasov formalism for extended relativistic mean field models: the crust-core transition and the stellar matter equation of state

Understand

The Vlasov formalism is extended to relativistic mean-field hadron models with non-linear terms up to fourth order and applied to the calculation of the crust-core transition density.

• The effect of the nonlinear $\omega\rho$ and $\sigma\rho$ coupling terms on the crust-core transition density and pressure, and on the macroscopic properties of some families of hadronic stars is investigated.
• For that purpose, six families of relativistic mean field models are considered.
• Within each family, the members differ in the symmetry energy behavior.
