| Abstract: |
We describe the motion of planetesimals in a protoplanetary nebula in terms of a fractal and irreversible process. As a consequence the equation of dynamics can be given a Schrödinger-like form. Its solutions yield a planetesimal distribution showing peaks of probability for semi-major axes normalized to star mass a/M ∝ n2 and eccentricities e = k⁄n, where k and n are integers. The current observational data on exoplanets support this theoretical prediction (done before their discovery). |
