title: Is dissipation important in neutron star mergers?
abstract:
Neutron star mergers are laboratories for hot and dense nuclear matter, in which there are large changes of temperature and density that happen in milliseconds. This means that mergers can probe dynamical properties that may help us to uncover exotic phases of ultra-dense matter. I will describe some of these properties, and then focus on the most promising, bulk viscosity. I will explain how bulk viscosity arises and how it might have a significant effect in a merger.
