Scientific paper

In order to estimate an upper limit to the normal optical depth of this putative ring we used an analytical model of an impact-generated dust ring proposed by Krivov et al. 2003 and Porter et al. 2010. By comparing our numerical results, which gives the width and lifetime of this ring and the mass production rate of the escaping dust, the maximum normal optical depth of a ring located near the orbits of Nix and Hydra is τ~10-11. This value, lower than previous estimatives, is consistent with a very tenuous ring of debris.
