摘要：

We present a RMF model including chiral SU(3) potential which is suggested form strong coupling limit of lattice QCD and we discuss nuclear star in this chiral SU(3) RMF model and show an effect to nuclear star maximum mass by introducing this potential. The calculation results in soft EOS which imcomressibility is as similar as empirical value. However, when we mind an appearance of hyperon, estimated nuclear star maximum mass underestimates the observable data. We suppose we have to investigate re-stiffen mechanism in high baryon density phase.
