The effect of site dilution on the magnetization and on the density of states (DOS) of a spin-S antiferromagnetic Heisenberg-model in the honeycomb lattice is studied using linear spin wave theory. For a given value of dilution the linearized Hamiltonian is solved in real space. The DOS is computed
