In a former work, we have shown the existence of smooth shock profiles for a model of nonequilibrium radiative hydrodynamics. In this Note, we show that such shock profiles are asymptotically stable for zero mass perturbation. Following the case of viscous shock profiles, the analysis relies on energy estimates for the integrated system.

Dans un précédent travail, nous avons montré l'existence de profils de choc pour un modèle de transfert radiatif hors-équilibre. Dans cette Note, nous montrons que de tels profils de choc sont asymptotiquement stables pour des perturbations de masse nulle. Comme dans le cas des profils de choc visqueux, l'analyse repose sur des estimations d'énergie pour le système intégré.
