Circumstellar dust is of prime importance for the evolution of Asymptotic Giant Branch (AGB) and Red Supergiant (RSG) stars, and it can be used to study/constrain their (circum)stellar parameters and evolution. The dust shows spectral features at infrared (IR) wavelengths, which are sensitive to the dust (grain) properties.
Modeling IR spectra can be tedious and time consuming. Often there are many (circum)stellar parameters to be fitted, and the solutions are not unique. Here I present the IDL code ICED, which automatically and objectively fits the IR emission of circumstellar dust, with an application to the IR spectrum of IRC+10216.
