    "abstract": "We calculate the in-medium $D$ meson self-energies in a hot pion gas induced\nby resonance interactions with pions. The appropriate resonances in the {\\it\ns},~ {\\it p} and {\\it d} waves of the $D$ meson-pion pair are represented by\nlow lying scalar, vector and tensor $D^*$ mesons. At temperatures around 200\nMeV the D-meson mass drops by $30~ \\rm {MeV}$ and the scattering width grows up\nto $60~ \\rm {MeV}$. Similar medium effects are found for the $D^*$ vector\nmesons. This opens and/or enhances the decay and/or dissociation channels of\nthe charmonium states $\\Psi^\\prime$, $\\chi_c$ and $J/\\Psi$ to $D \\bar D,~D^*\n\\bar D,~D \\bar D^* ,~D^* \\bar D^*$ pairs in pion matter.",
