| Abstract: |
We review the current approaches to the interpretation of 8-13 μm thermal emission spectra and present new analyses on a number of aspects of them. Topics include the relation between color temperature and kinetic temperature, the effects of size and optical constants on temperature, the ubiquitous existence of molecular disorder, the effects of nonspherical particles and the wavelength shift of lattice resonances with particle size. We develop the analyses around the silicate emission feature observed in many comets and discuss why comets are ideal subjects for advancing our knowledge of thermal emission from small particles. The results are broadly applicable to all cosmic dust. |
