Very long-term relaxation of harmonic 1D self-gravitating systems
Kerwann Tep, Jean-Baptiste Fouvry, Christophe Pichon
One-dimensional self-gravitating systems admit genuine thermodynamical equilibria. For systems with strictly monotonic orbital frequency profile, the Landau and Balescu-Lenard theo…

Linear response of rotating and flattened stellar clusters: the oblate Kuzmin-Kutuzov Stäckel family
Kerwann Tep, Christophe Pichon, Michael S Petersen
This paper investigates the linear response of a series of spheroidal stellar clusters, the Kuzmin-Kutuzov Stäckel family, which exhibit a continuous range of flattening and rotat…

On the long-term evolution of razor-thin galactic discs: Balescu-Lenard prediction and perspectives
Mathieu Roule, Jean-Baptiste Fouvry, Christophe Pichon +1
In the last five decades, numerical simulations have provided invaluable insights into the evolution of galactic discs over cosmic times. As a complementary approach, developments…
