Description

We present a holographic framework designed to model strongly interacting matter relevant for the interiors of neutron stars. This approach captures key features of QCD at finite density and provides a controlled approximation for the nonperturbative regime inaccessible to standard methods. By calibrating the model to lattice data at low density, we obtain predictions for the equation of state across a wide density range. Our results are consistent with known nuclear matter properties at low densities and smoothly interpolate to the deconfined phase at higher densities, consistent with pQCD. We discuss implications for neutron star phenomenology and constraints from astrophysical observations.
