Thermal Emission of Cometary Dust Grains

The mineralogical composition of cometary dust particles is often determined by analyzing thermal emission spectra of cometary comae obtained by spaceborne observatories. Classically, synthetic spectra of spherical single-component grains are calculated for different minerals and grain sizes. By combining such synthetic spectra and requiring that the observed spectra thereby are reproduced, one can determine the composition of cometary dust grains and the relative abundances of different species. In reality, however, comet dust grains are non-spherical and consist of intimately mixed minerals, which means that the classical procedure is inaccurate. The project consist of investigating the severity of such inaccuracies by performing light scattering and thermal emission calculations for non-spherical multi-component dust grains, using state-of-the-art software.
