203.1 Introduction It has been investigated [1] that the material in the core of compact stars may consist of quark matter. Compact stars which are absolutely made up of quark matter, additionally there maybe a small layer of a crust of nuclei are called Quark stars. Witten [1] claim that the quarks matter may be the true ground state of nuclear dense matter in the compact stars. Theoretical researchers generally admit that the ground state of QCD with three flavors is the color-flavor-locked (CFL) phase [2]. In present work, we propose to investigate the quarks matter within the framework of self consistent chemical potential dependent quarks quasiparticle model. Here, a set of EOS is employed to investigate the mass-radius relationship of quarks star.
