Bulk viscosity of strange quark matter: Urca versus non-leptonic processes
arXiv:astro-ph/0703016 · doi:10.1103/PhysRevD.75.125004
Abstract
A general formalism for calculating the bulk viscosity of strange quark matter is developed. Contrary to the common belief that the non-leptonic processes alone give the dominant contribution to the bulk viscosity, the inclusion of the Urca processes is shown to play an important role at intermediate densities when the characteristic r-mode oscillation frequencies are not too high. The interplay of non-leptonic and Urca processes is analyzed in detail
