We consider a quarkyonic matter model in which, for large values of density and Fermi energies, weassume particles as quasiparticles where the low Fermi momentum states are occupied by quarks and the higherstates in phase space are occupied by baryons. This idea has the aim to explain with a consistent way the phasetransition in the interior of a neutron star or a hybrid star and to provide an equation of state which can produceneutron stars with masses greater than 2Msun without violating causality. At extremely high density, quarkyonicmatter is inferred from the properties of QCD when Nc is large and is a qualitative way to describe the particlesin the momentum space. This state of matter can provide the sound velocity as a non-monotonic function of thebaryon density which for higher values of density tends asymptotically to the conformal limit 1/√3. (EN)
