We develop a non-parametric method for inferring the universal neutron star (NS) equation of state (EOS) from gravitational wave (GW) observations. Many different possible realizations of the EOS are generated with a Gaussian process conditioned on a set of nuclear-theoretic models. These synthetic EOSs are causal and thermodynamically stable by construction, span a broad region of the pressure-density plane, and can be selected to satisfy astrophysical constraints on the NS mass.

Nonparametric inference of neutron star composition, equation of state, and maximum mass with GW170817
The detection of GW170817 in gravitational waves provides unprecedented constraints on the equation of state (EOS) of the ultra-dense matter within the cores of neutron stars (NSs). We extend the
Bayesian Nonparametric Inference of the Neutron Star Equation of State via a Neural Network
A new nonparametric method to reconstruct the equation of state (EoS) of a neutron star with multimessenger data and finds that in the high-density region, the 90% lower limits of cs2/c2 are above 1/3, which means that the so-called conformal limit is not always valid in the neutron stars.
