Extended Data Fig. 1

Ranges of allowed equations of state (a), and the corresponding neutron star mass–radius relations (b), are displayed as obtained with the speed-of-sound (green region), piecewise polytropic (black dotted lines), and spectral (orange dashed lines) interpolation methods. In panel b, we show also equations of state that fail to reproduce 2M stars (cyan region) and those that lead to tidal deformabilities outside the range determined by the gravitational-wave event GW17081719 (purple region).
