abstract: 'In the present work we investigate the main differences in the lead neutron skin thickness, binding energy, surface energy and density profiles obtained with two different density dependent hadron models. Our results are calculated within the Thomas-Fermi approximation with two different numerical prescriptions and compared with results obtained with a common parametrization of the non-linear Walecka model. The neutron skin thickness is a reflex of the equation of state properties. Hence, a direct correlation between the neutron skin thickness and the slope of the symmetry energy is found. We show that within the present approximations the asymmetry parameter for low momentum transfer polarized electron scattering is not sensitive to the model differences.'

Introduction
============

The relation between neutron star properties which are obtained from adequate equations of state (EoS) and the neutron skin thickness has long been a topic of investigation in the literature. The details of this relation and the important quantities to be discussed have been well established in [@tb01], where
