Unified weak and strong coupling framework for nuclear matter and neutron stars

Ab initio methods using weakly interacting nucleons give a good description of condensed nuclear matter up to densities comparable the saturation density. At higher palpable strong interactions between overlapping become important; we propose that will continuously switch over follow holographic model in this region. In order implement this, construct hybrid equations state (EoSs) where various models are used for low density matter, and V-QCD is non-perturbative high as well quark matter. We carefully examine all existing constraints from astrophysics compact stars discuss their implications EoSs. Thanks stiffness EoS obtain large family viable EoSs passing constraints. find cores neutron unstable due strongly first deconfinement transition, predict bounds on tidal deformability radius stars. By relying universal relations, also constrain characteristic peak frequencies gravitational waves produced star mergers.
