An Application of Fractals to Stellar Dynamics

Abstract:
Fractals are geometric objects that describe real life systemsmore accurately than idealized Euclidean objects. In particular, they provide a simple yet powerful tool to study the non-Gaussian properties of random processes. In this talk, I will describe fractals from an astronomer's point of view, i.e., through examples and general properties. Then, I will show a simple application in stellar dynamics, where we observe a non-Gaussian random walk.  For this process, fractal analysis not only reveals the non-Gaussian feature, but also gives the relevant time scales.
