We compute finite temperature properties of a recently proposed “excluded volume” model of quarkyonic matter under thermodynamic conditions found in binary neutron star mergers. To do so, we extend this model by introducing finite temperature distribution functions and entropy functionals. The main effect of temperature is to decrease by a small amount the baryon density at which the quarkyonic phase emerges, and to increase the total density of quarks. To the extent this model describes reality, we conclude that hot environments such as neutron star mergers are more likely to host deconfined quark matter than their zero temperature counterparts.
