These \"viscous-dynamical\" ejecta are launched during merger due to the thermalization of mass exchange streams between the secondary and the primary neutron star. They are characterized by asymptotic velocities extending up to ${\\sim} 0.8\\, c$, and have masses that depend on the efficiency of the viscous mechanism.
