摘要：
We study the thermodynamic properties of the color-flavored-locked (CFL) quark matter in finite temperature and strong magnetic field cases within the confined-isospin-density-dependent-mass model. We find that considering the CFL phase in quark star (QS) matter can significantly influence the equation of state as well as the properties of QSs at finite temperature or under strong magnetic fields. In particular, our results indicate that the polytropic index becomes anisotropic under magnetic fields and decreases with the increment of the star mass at different isentropic stages of QSs.
