The curves on the left of the solid circles represent the equilibrium sequences for the hybrid stars with core composed of the quark matter in the CFL phase. The curves between the solid circles and triangles represent the hybrid stars with 2SC quark matter core. The absence of solid triangle on a curve means that the hybrid stars contain quark matter only in the CFL phase. 16
