英文摘要	In this paper we introduce an equation of state (EOS) of quark matter within the framework of Dyson-Schwinger equations to study the structure of compact stars. The smooth crossover from hadronic matter to quark matter in the hybrid star is studied. We compare different strategies to obtain crossover EOSs and find a new way to construct two-solar-mass hybrid stars with even a relatively soft quark EOS, while earlier works showed that the quark EOS should be stiff enough to support a massive hybrid star.
