Abstract: The property and component structure of compact stars are calculated with relativistic mean field theory(RMF). For neutron stars, a density-dependent
magnetic field is considered. For hybrid stars, the quark phase is solved using Dyson-Schwinger quark model. In both cases, the delta-meson channel interaction is
considered in hadron phase. The magnetic field will support a neutron star exceeding two-solar mass, while the delta-meson will increase the radius of the star. The
introduction of quark phase will generally reduce the mass of the compact star, while the phase transition from hadron phase to quark phase is delayed by delta-meson
interaction.
