Non-parametric Inference of the Neutron Star Equation of State with Gravitational Waves

GW170817 provides the first opportunity to constrain the supranuclear equation of state within the core of neutron stars using gravitational-wave observations. As more systems are detected, equation of state modeling systematics could become as significant as statistical uncertainty from the resulting combined measurement. I introduce a non-parameteric inference scheme for the equation of state that supports much broader model freedom and therefore fewer systematic errors than other approaches. Furthermore, this non-parametric scheme can be tuned to resemble existing nuclear theoretic models or specific nuclear phenomenology to a specifiable degree self-consistently. I will summarize the equation of state constraints obtained from GW170817 using this approach and discuss possible implications for nuclear theoretic models.
