In this poster, I will present results from a recent study aimed at finding the most plausible Equation of State (EoS) for neutron star matter, combining available first principles calculations with up-to-date observational data. Our EoSs are composed of piecewise polytropes interpolating between known limits from quantum Monte Carlo at low densities and perturbative QCD at high densities. Further constraints are obtained from neutron star mass measurements as well as from observations of thermonuclear X-ray bursts that can be used to evaluate both the masses and the radii of certain neutron stars in binary systems. Our results indicate that neutron star observations can place constraints on the behavior of QCD matter even at very high densities.
