In this paper, we first provide a derivation of compressible nonisentropic Hall-magnetohydrodynamic (Hall-MHD) system from generalized Ohm's law. Then, we prove the global existence of strong solutions for the compressible nonisentropic Hall-MHD model based on the standard energy method in -framework. Finally, optimal decay rates of strong solutions in -norm are obtained if the initial data
