  Neutron star matter is investigated in a hadronic chiral model approach using
the lowest flavor-SU(3) multiplets for baryons and mesons. The parameters are
determined to yield consistent results for saturated nuclear matter as well as
for finite nuclei. The influence of baryonic resonances is discussed. The
global properties of a neutron star such as its mass and radius are determined.
Proto-neutron star properties are studied by taking into account trapped
neutrinos, temperature and entropy effects.
