The effect of Nix and Hydra on the putative Pluto-Charon dust cloud

► Particle-tracing model of the Pluto-Charon dust environment including Nix and Hydra. ► Optical depth predictions of the dust ring at 0.5, 5.0 and 50.0μm. ► Prediction for the micron-sized dust flux to New Horizons during the Pluto fly-by.
