Waves and instabilities in dissipative rotating superfluid neutron stars

We discuss wave propagation in rotating superfluid neutron star cores, taking into account the vortex-mediated mutual friction force. For models where the two fluids corotate in the unperturbed state, our analysis clarifies the role of chemical coupling and entrainment for sound and inertial waves. We also investigate the mutual friction damping, providing results that demonstrate the well-known f...
