Quarkyonic matter suppresses neutron-star $g$ modes and reverses their mass trend

Gravity (g) modes are the only neutron-star oscillations that report on the composition of dense matter rather than on its stiffness, and work on hybrid stars has established that a first-order quark transition raises their frequency. Quarkyonic matter does the opposite. Quark-nucleon chemical equilibrium is maintained...
