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.
