@article{Gusakov2013DissipationIR, title={Dissipation in relativistic superfluid neutron stars}, author={Mikhail E. Gusakov and Elena M. Kantor and Andrey I Chugunov and Leonardo Gualtieri}, journal={Monthly Notices of the Royal Astronomical Society}, year={2013}, volume={428}, pages={1518-1536} }

We analyze damping of oscillations of general relativistic superfluid neutron stars. To this aim we extend the method of decoupling of superfluid and normal oscillation modes first suggested in [Gusakov & Kantor PRD 83, 081304(R) (2011)]. All calculations are made self-consistently within the finite temperature superfluid hydrodynamics. The general analytic formulas are derived for damping times due to the shear and bulk viscosities. These formulas describe both normal and superfluid neutron…
