摘要
The bulk viscosity due to the non-leptonic process involving hyperons in K-condensed matter is discussed here. We find that the bulk viscosity is modified in a superconducting phase. Further, we demonstrate how the exotic bulk viscosity coefficient influences r-modes of neutron stars which might be sources of detectable gravitational waves.
