Radiation transport models are constructed for the dust shells of the hydrogen deficient supergiant star R Coronae Borealis (R CrB). IRAS observations of R CrB are used as constraints in selecting the model parameters. Based on suggestions from earlier work, a double-shell model is employed as a standard configuration for R CrB. The first shell is a hot inner shell of radius 5 arcsec surrounding t...
