Abstract：
Taking medium effects into account, we calculate the bulk viscosity of strange quark matter in high temperature approximation using a consistent thermodynamics method in quasi particle description. We find that medium effects have great influence to the bulk viscosity of strange quark matter, which leads to the result that two flavor superconductivity (2SC) is not excluded by pulsar data, unlike Madsen's result.
