Abstract	The possibility of observationally discriminating between various types of neutron stars, described by different equations of state of the nuclear matter, as well as differentiating neutron stars from other types of exotic objects, like, for example, quark stars, is one of the fundamental problems in contemporary astrophysics. We consider the possibility that different types of quark stars, in both normal and superconducting CFL (Color-Flavor-Locked) phase can be differentiated among themselves, and from neutron stars, by the study of the emission properties of the accretion disks. Particular signatures appear in the electromagnetic spectrum, thus leading to the possibility of directly testing the equation of state of the dense matter by using astrophysical observations of the spectra of the accretion disks.
