Probing exotic matter in neutron star cores with g-mode oscillations

Sophia Han

The neutron star interior reaches ultra-high densities with its composition details unknown. Gravitational wave emissions from neutron stars are promising probes that can help reveal novel phases of matter. I will describe a first study of the principle g-mode oscillation in hybrid stars containing quark matter through hadron-quark crossover transition, and compare with results obtained for a first-order phase transition via Gibbs construction. I will discuss the distinct behaviors of the adiabatic and equilibrium sound speeds in various models of the equation of state (EoS) for neutron-star matter, as well as their connections to astrophysical observables.
