Abstract
We show that for neutrino-transparent npe matter, the equation-of-state dependence of bulk-viscous transport coefficients can be completely determined by the nuclear symmetry energy. We also show that changes in the symmetry energy slope L can result in orders of magnitude changes in the bulk viscosity.
