Query: Neutron stars within the Skyrme model   The Skyrme model is a low energy effective field theory of strong
interactions where nuclei and baryons appear as collective excitations of
pionic degrees of freedom. In the last years, there has been a revival of
Skyrme's ideas and new related models, some of them with BPS bounds
(topological lower energy bounds), have been proposed. It is the aim of this
paper to review how they can be applied to the study of neutron stars allowing
for a description by means of topological solitons. We will focus on different
aspects as the equation of state or the mass-radius relation, where we find
that high maximal masses are supported.
