How long it survives and what it looks like encodes information about the equation of state at densities far beyond anything accessible in a terrestrial experiment.</p> <p>This paper constructs quasi-stationary equilibrium sequences of hyper-massive neutron stars using exotic equations of state that include strange quark matter, hyperons, and other non-nucleonic degrees of freedom. We map out how the remnant mass, angular momentum, and oscillation frequencies change with the underlying microphysics, giving a theoretical foundation for interpreting post-merger gravitational wave signals from next-generation detectors.</p> <p>Published in Journal of Astrophysics and Astronomy (2022)</p>
