@article{Yoshida2003rmodesIR, title={r-modes in relativistic superfluid stars}, author={Shijun Yoshida and Umin Lee}, journal={Physical Review D}, year={2003}, volume={67}, pages={124019} }
We discuss the modal properties of the r modes of relativistic superfluid neutron stars, taking account of the entrainment effects between superfluids. In this paper, the neutron stars are assumed to be filled with neutron and proton superfluids and the strength of the entrainment effects between the superfluids are represented by a single parameter $\ensuremath{\eta}.$ We find that the basic properties of the r modes in a relativistic superfluid star are very similar to those found for a…
