%X Density-dependent relations among saturation properties of symmetric
nuclear matter and hyperonic matter, properties of hadron-(strange) quark
hybrid stars are discussed by applying the conserving nonlinear s-w-r hadronic
mean-field theory. Nonlinear interactions that will be renormalized as
effective coupling constants, effective masses and sources of meson equations
of motion are constructed self-consistently by maintaining thermodynamic
consistency to the mean- field
approximation. The coupling constants expected from the hadronic mean-field
model and SU (6) quark model for the vector coupling constants are compared;
the coupling constants exhibit different density-dependent results for effective
masses and binding energies of hyperons, properties of hadron and hadron-quark
stars. The nonlinear s-w-r hadronic
mean-field approximation with or without vacuum fluctuation corrections and
strange quark matter defined by MIT-bag model are employed to examine
properties of hadron-(strange) quark hybrid stars. The hadron- (strange) quark hybrid
stars become more stable at high densities compared to pure hadronic and pure
strange quark stars.
