Modelling of the atmospheric environment on and around cool M giants and dwarfs
Abstract
A numerical method involving radiative transfer techniques has been developed to model the gas/dust environment around cool red giants. The method provides a large amount of information as to the physical conditions within the model dust shell, such as the temperature gradient and intensity distributions throughout the shell, as well as predicting the emergent fluxes. Although the method has so far been applied only to a few examples of carbon-rich and oxygen-rich stars, it is apparent from the results that they are an improvement upon previous work. We suggest here where further enhancements in the technique are possible.
