Abstract：
A hybrid star with a pure quark core, a hadron crust and a mixed phase between the two is considered. The relativistic mean field model for hadron matter and the effective mass bag model for quark matter are used to construct the equation of state for hybrid stars. The influences of medium effects that are parameterized by the strong coupling constant have been discussed on the configuration of rotating stars. The strong coupling constant is a prominent factor that influences the properties of rotating hybrid stars.
