Modeling Infrared (IR) Emission of Novae

IR emission of dusty classical novae is modeled for a blob- ring shell geometry having carbon (graphite) grains in the blobs and silicate grains in the ring. Specific characteristics of the temporal and wavelength dependence of the theoretical IR fluxes from the model are predicted and compared with observations of some classical novae. The theoretical calculations of the model show general agreement with observations.
