On the Structure of Saturn's Rings.

TL;DR: Saturn disk monochromatic albedos observation by multicolor photoelectric photometry, comparing with Jupiter as discussed by the authors, showing that the latter is more stable than the former.

TL;DR: The photometric observations of Saturn's rings made by Camichel (1958a), and Focas and Dollfus (1969) are studied in this article, where it has been found that at large elevation angles multiple scattering between ring particles, and at small elevation angles deviation from Seeliger's principal photometric theory can explain the observations.

TL;DR: In this paper, the effect of the chemical composition of the ice on its collisional properties has not yet been studied, but it is known that simple chemicals such as methanol and formic acid are present in cold protostellar regions alongside the dominant water ice; they are also likely to be incorporated into planets which form in protoplanetary disks and planetary ring systems.

TL;DR: In this paper, a simple semiquantitative explanation is presented which accounts both for the presence of the azimuthal brightness variations in Saturn's ring A and for their absence in ring B.
