  We investigate the structure attained by neutron star matter with proton to
neutron ratios ranging from x=0.1 to 0.5, densities in the range of 0.02 fm-3
to 0.085 fm-3, and temperatures T<4 MeV. In particular we study the pasta
shapes and the phase changes previously observed in nuclear matter, as well as
the behavior of the symmetry energy. We corroborate the existence of
homogeneous to non-homogeneous phase transitions, and the different values of
the symmetry energy at different densities and temperatures.
