Collisional amplification of density fluctuations in Saturn's rings
J. Lukkari
Department of Astronomy, University of Oulu, Oulu, Finland
The encounter of Voyager 1 with Saturn in November 1980 revealed the ringlet structure of its rings. As the theoretical examination of the collisional evolution of keplerian systems1,2 had predicted such a structure in dense matter as a consequence of amplified fluctuations in density, some new computer simulations have now been carried out to check this effect. These simulations actually led to a strong, irreversible growth in the density maximum.
