Description
We consider a response of kaon-condensed phase in hyperon-mixed matter [(Y+K) phase] to neutron-star oscillations. We obtain the sound velocity propagating in the (Y+K) phase out of chemical equilibrium with respect to the relevant weak reactions, searching for signals unique to kaon condensation associated with typical gravitational wave modes. The dissipation of vibrational energy including the (Y+K) phase and its damping time scale are also investigated.
