A Semi-Supervised Variational Autoencoder for Generating Neutron Star Equations of State
Tianqi Zhao, Fanglida Yan, Alex Ross +1
We develop a semi-supervised variational autoencoder (SSVAE) framework to reconstruct and generate neutron star (NS) equations of state (EOS). The SSVAE consists of an encoder netw…
A New Bayesian Framework with Natural Priors to Constrain the Neutron Star Equation of State
Boyang Sun, Tianqi Zhao, James M. Lattimer
We propose a new Bayesian framework to infer the neutron star equation of state (EOS) from mass and radius observations and neutron matter theory by defining priors that directly p…
Observable Signatures of a Quarkyonic Phase in Neutron Stars
Probit J Kalita, Tuhin Malik, Tianqi Zhao +2
Quarkyonic matter in \(β\)-equilibrium is a potential description of cold dense matter in neutron stars (NSs), that introduces non-interacting quarks alongside nucleons and lepton…
Correlations between the Neutron Star Mass-Radius Relation and the Equation of State of Dense Matter
Boyang Sun, James M. Lattimer
We develop an analytic method of inverting the Tolman-Oppenheimer-Volkoff (TOV) relations to high accuracy. In principle, a specified $\mathcal{E}\mbox{-}P$ relation gives a unique…
