Lonely planets and light belts: the statistical mechanics of planetary systems
Martedì 22 settembre 2020 alle ore 14:30, il prof. Benedetto Scoppola dell'Università Tor Vergata, terrà il seminario dal titolo "Lonely planets and light belts: the statistical mechanics of planetary systems"

Abstract
we propose a notion of stability, that we call $epsilon$-stability, for systems of particles interacting via Newton's gravitational potential, and orbiting around a much bigger object. For these systems the usual thermodynamical stability condition, ensuring the possibility to perform the thermodynamical limit, fails, but one can use as relevant parameter the maximum number of particles that guarantees the $epsilon$-stability. With some judicious but not particularly optimized estimates, borrowed from the classical theory of equilibrium statistical mechanics, we show that our model has a good fit with the data observed in the Solar System, and it gives a reasonable interpretation of some of its global properties. Joint work with Gabriella Pinzari and Alessio Troiani.
