| Popis: | In the present work we study the equation of state for asymmetric hadronic matter, to be applied in neutron star structure calculation. The delta-rich hadronic stellar matter condensate is studied in the context of mean-field approximation in an extended Walecka's theory version, including the Rarita–Schwinger 3/2-spinor to the hadronic sector. The leptonic sector is also incorporated in beta-equilibrium to the dense stelar medium composition. The role of neutrino trapping for the the formed photo-neutron structure including delta matter in its composition is discussed. |
