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. To cite this article: C. Lin, J.-F. Coulombel, T. Goudon, C. R. Acad. Sci. Paris, Ser.

Dans un precedent travail, nous avons montre l'existence de profils de choc pour un modele de transfert radiatif hors-equilibre.
