An analytic parameterization of self-gravity wakes in Saturn's rings, with application to occultations and propellers
Matthew S. Tiscareno, Randall P. Perrine, Derek C. Richardson +4
We have developed a semi-analytic method of parameterizing N-body simulations of self-gravity wakes in Saturn's rings, describing their properties by means of only 6 numbers: 3 opt…

A Symplectic Integrator for Hill's Equations
T. Quinn, R. P. Perrine, D. C. Richardson +1
Hill's equations are an approximation that is useful in a number of areas of astrophysics including planetary rings and planetesimal disks. We derive a symplectic method for integr…
