Popis: | Thermal IR spectroscopy of Saturn's A and B rings in the 8- to 13-μm range reveals a smooth, Planck-like continuum with no spectral structure that could be attributed to optically thin water ice or silicate dust. The brightness temperatures of the A and B rings obtained by fitting a Planck function to the spectra were 90.3±0.9 and 90.5±0.6 K, respectively, in good agreement with and extending earlier photometric measurements. |
