− Recent advances in experiments of the symmetry energy of nuclear
matter and
in neutron star observations, yield important new insights on the
equation of
state of neutron matter at nuclear densities. In this regime the EOS of
neutron matter plays
a critical role in determining the mass-radius relationship for
neutron stars. We
show how microscopic calculations of
neutron matter make clear predictions for the relation between the
isospin-asymmetry energy of nuclear matter and its density
dependence, and the
maximum mass and radius for a neutron star.On the other side, the properties of inhomogeneous neutron
matter at low
to moderate densities are very important to describe the neutron
star crust,
and we show how microscopic calculations of confined neutrons can
put severe
constraints on density functionals used to describe heavy nuclei
and the crust.
