Abstract
The structure of compact star core filled by gluon matter plasma is investigated within the fluid-like QCD framework. The energy momentum tensor, density and pressure relevant for gluonic plasma having the nature of fluid bulk of gluon sea are derived within the model. It is shown that the model provides a new equation of state for perfect fluid with only a single parameter of fluid distribution {\phi}(x). The results are applied to construct the equation of state describing the gluonic plasma dominated compact star core. The equations of pressure and density distribution are solved analytically for small compact star core radius. The phase transition of plasma near the core surface is also discussed.
