Approximating neutron-star radii using gravitational-wave only measurements with symbolic regression
A symbolic-regression fit, k2(M, log10 Lambda), approximates neutron-star radii from gravitational-wave-only mass and tidal-deformability measurements to within a few hundred meters for the tested equations of state.
