Description
Neutron stars (NSs) are the most massive known objects in the Universe. Their masses range from 1.2 to 2.3 solar masses, while their radii are in the range of ~10 km. The density increases towards the origin of the star, and can reach 4-6 times the normal nuclear density. The matter in these circumstances is organized by the strong interaction, and it is possible that quark-gluon plasma can be found inside the core. In this talk I will explore how these hybrid stars can be studied using effective models of QCD, and how astrophysical measurements constrain certain parameters of the model. Results from a recent Bayesian analysis will also be presented.
