The study of the internal composition of compact stars, such as hybrid stars (HSs), is of primary importance since they seem to be the only natural systems to possess the existence of quark matter and, at the same time, to be able to accumulate a sizeable amount dark matter (DM) in their interior. The research project will include both theoretical and modeling parts. The first one will be dedicated to the analytical formulation of the equation of state (EoS) of strongly interacting matter with the deconfinement phase transition between hadrons and quarks, considering the constraints coming from the astrophysical observations, nuclear matter and the results of quantum chromodynamics on the lattice. By modeling the thermal evolution of HSs, I will implement both the nuclear superfluidity/superconductivity and the quark superfluidity. The effect of DM on the nuclear and quark matter properties will be tested on existing data on compact stars’ cooling.
