Abstract :
In this paper, we study the asymptotic limit of a multidimensional non-isentropic radiation hydrodynamics model arising from astrophysics via non-relativistic regime. We first obtain the local existence of smooth solutions to the initial value problem. Then, we give a convergence result of the radiation hydrodynamics equations to the compressible and non-isentropic Euler equations.
