Barnabás Deme
Recent observations have confirmed the existence of rings around minor bodies in the outer Solar System. These objects may possess satellites as well. Here we analytically investig…

Thermodynamic blocking in self-gravitating systems
Barnabás Deme, Jean-Baptiste Fouvry
Building upon a thermodynamic formalism, we show that self-gravitating systems in hydrostatic equilibrium with a uniform density are maximal entropy states when submitted to pertur…

On the secular evolution of the semi-major axis in canonical formalism
Barnabás Deme
There are several astrophysical configurations where one is interested only in the long-term dynamical evolution. Although the first-order version of this approximation is usually…
