[47.07] IR Radiative Transfer with Transient Heating

K. A. Misselt, K. D. Gordon, G. C. Clayton (LSU), M. J. Wolff (SSI)

In order to study the evolutionary history of most astrophysical systems an accurate account of the effects of dust is necessary. We are currently extending our radiative transfer models to include infrared emission from dust. Presently,the model tracks UV and optical photons through an arbitrary mixture of gas, stars, and dust. Emission from dust includes emission from large grains in thermodynamic equilibrium with the radiation field as well as small grains and molecules that undergo transient heating. Here we present results from our model which include the effects of the transient heating and apply it to systems with simple geometries.
