Convex hull of a Brownian motion in confinement
M. Chupeau, O. Bénichou, S. N. Majumdar
We study the effect of confinement on the mean perimeter of the convex hull of a planar Brownian motion, defined as the minimum convex polygon enclosing the trajectory. We use a mi…
Mean cover time of one-dimensional persistent random walks
Marie Chupeau, Olivier Bénichou, Raphaël Voituriez
The cover time is defined as the time needed for a random walker to visit every site of a confined domain. Here, we focus on persistent random walks, which provide a minimal model…
The ballistic transport instability in Saturn's rings III: numerical simulations
Henrik Latter, Gordon Ogilvie, Marie Chupeau
Saturn's inner B-ring and its C-ring support wavetrains of contrasting amplitudes but with similar length scales, 100-1000 km. In addition, the inner B-ring is punctuated by two in…
The ballistic transport instability in Saturn's rings II: nonlinear wave dynamics
Henrik Latter, Gordon Ogilvie, Marie Chupeau
The ejecta discharged by impacting meteorites can redistribute a planetary ring's mass and angular momentum. This `ballistic transport' of ring properties instigates a linear insta…
