The static spherically symmetric quark star structure is calculated by using an equation of state which takes into account the superconducting color-flavor locked phase of the strange quark matter. Some fundamental aspects of QCD (asymptotic freedom and confinement) are considered by means of a phenomenological description of the deconfined quark phase, namely, the density-dependent quark mass model. The effects from the strong interaction described by these models can affect the equation of state of the quark matter substantially. In this work we discuss the influence of these effects on the conventional mass-radius relationship of quark stars. Massive quark stars are found due to the stiffness of the equation of state at low densities, when reasonable values of the superconducting gap, taken as a free parameter, are used.
