Abstract :
We have implemented and validated a model for the radiative transfer in molecular clouds and studied the water emission line for Comet 67 P/Churyumov-Gerasimenko. Results are reported that show that the spectral profiles for water emission lines depend on the physical properties of the coma. This tool will be used to interpret observations by MIRO and will help build hydrodynamics models of comets.
