Diffusion as a leading dissipative mechanism in superconducting neutron stars

Despite the fact that different particle species can diffuse with respect to each other in neutron star (NS) cores, effect of diffusion on various phenomena associated NS oscillations is usually ignored. Here we demonstrate be extremely powerful dissipative mechanism superconducting NSs. In particular, it much more efficient than shear and bulk viscosities. This result has important implications for damping times oscillations, development saturation dynamical instabilities NSs, excitation coupling oscillation modes during late inspiral binary
