Tree code simulations of planetary rings

  title={Tree code simulations of planetary rings},
  author={Derek C. Richardson},
A tree code method that incorporates a local shearing disc model and fourth-order integration algorithm is applied to the problem of planetary rings, with particular emphasis on the dynamics of Saturn's B ring. The new code, described in detail elsewhere, allows for particle self-gravity, a distribution of particle sizes, and surface friction (particle spin). Important changes made to the original code, to ensure an accurate treatment of collisions under severe high-density conditions, are… CONTINUE READING
