  We investigate the correlation between nuclear neutron radii and the radius
of neutron stars. We use a well-established hadronic SU(3) model based on
chiral symmetry that naturally includes non-linear vector meson and scalar
meson - vector meson couplings. The relative strengths of the couplings modify
the nuclear isospin-dependent interactions. We study the dependence of nuclear
and neutron star radii on the coupling strengths. The relevance of the results
for parity-violating electron-nucleus scattering and the URCA process in
neutron stars is discussed.
