What Can We Learn about the Unstable Equation-of-state Branch from Neutron Star Mergers?
The equation of state (EOS) of dense strongly interacting matter can be probed by astrophysical observations of neutron stars (NS), such as X-ray detections of pulsars or the measurement of the tidal deformability of NSs during the inspiral stage of NS mergers.These observations constrain the EOS at most up to the density of the maximum-mass config
