  "abstract": "A granular gas subjected to a permanent injection of energy is described by means of hydrodynamic equations derived from a moment expansion method. The method uses as reference function not a Maxwellian distribution $f_{\\sf M}$ but a distribution $f_0 = \\Phi f_{\\sf M}$, such that $\\Phi$ adds a fourth cumulant $\\kappa$ to the velocity distribution. The formalism is applied to a stationary conductive case showing that the theory fits extraordinarily well the results coming from our molecular dynamic simulations once we determine $\\kappa$ as a function of the inelasticity of the particle-particle collisions. The shape of $\\kappa$ is independent of the size $N$ of the system.",
