摘要：

The deconfinement phase transition from hadronic matter to quark matter in the interior of compact stars is investigated The hadronic phase is described in the framework of relativistic mean-field theory, where the scalar-isovector delta-meson effective field is also taken into account The MIT bag model for describing a quark phase is used The changes of the parameters of phase transition caused by the presence of a delta-meson field are explored Finally, alterations in the integral and structural parameters of hybrid stars due to both a deconfinement phase transition and inclusion of a delta-meson field are discussed
