In this talk, I will focus on the behavior of matter at high densities in compact stars, in particular, the possibility of phase transitions in the QCD phase diagram and their effect on the physics of compact stars. Specifically, I will explore the case of strong first-order phase transition among the dense quark matter phases and the emergence of twin and triplet configurations of compact stars. I will also present the neutrino cooling of compact stars with quark cores and confront them with the possible transient in the young neutron star in Cas A. Finally, I will discuss the implications of the recent detection of gravitational wave from a neutron star binary inspiral for tidal deformability and the equation of state of dense matter.
