Constraints On The Equation Of State Of Strange Quark Matter With Structure Of Hybrid Stars

QCD predicts that the retreat phase transition occurs at high temperature or high density.Inside the neutron star is high density environment,there may be quark matter.This challenges the traditional neutron star model and related astrophysics,and the essence of pulsar's central celestial body needs to be further explored.By understanding the properties of the high density nuclear matter,this paper analyzes the various possibilities of the internal matter in the neutron star,introduces the challenges facing the traditional neutron star model,and expounds the description of the hadron matter,the MIT bag model and the perturbation QCD correction by the theory of the relativistic mean field,and discusses the structure and structure characteristics of the sub star in the quark matter.Based on the occurrence of mixed star phase transitions and the existence of stable mixed phases,a method for limiting the parameters of the equation of state of strange quark matter is proposed.The calculation shows that the QCD correction can make the equation of state of the hybrid star hardened,so that the maximum mass of the mixed star reaches or exceeds 2.0M?.After satisfying the phase transformation physics,stable mixing phase conditions and observation results,we give the limit of the parameters of the state equation of the singular matter,and find that the parameter range is smaller than the absolute steady state condition.
