Secular diffusion in discrete self-gravitating tepid discs II: accounting for swing amplification via the matrix method
Jean-Baptiste Fouvry, Christophe Pichon, John Magorrian +1
The secular evolution of an infinitely thin tepid isolated galactic disc made of a finite number of particles is investigated using the inhomogeneous Balescu-Lenard equation expres…
Secular diffusion in discrete self-gravitating tepid discs I : analytic solution in the tightly wound limit
Jean-Baptiste Fouvry, Christophe Pichon, Pierre-Henri Chavanis
The secular evolution of an infinitely thin tepid isolated galactic disc made of a finite number of particles is described using the inhomogeneous Balescu-Lenard equation. Assuming…
Self-gravity, resonances and orbital diffusion in stellar discs
Jean-Baptiste Fouvry, James Binney, Christophe Pichon
Fluctuations in a stellar system's gravitational field cause the orbits of stars to evolve. The resulting evolution of the system can be computed with the orbit-averaged Fokker-Pla…
Secular resonant dressed orbital diffusion II : application to an isolated self similar tepid galactic disc
Jean-Baptiste Fouvry, Christophe Pichon
The main orbital signatures of the secular evolution of an isolated self-gravitating stellar Mestel disc are recovered using a dressed Fokker-Planck formalism in angle-action varia…
Secular resonant dressed orbital diffusion I : method and WKB limit for tepid discs
Jean-Baptiste Fouvry, Christophe Pichon, Simon Prunet
The equation describing the secular diffusion of a self-gravitating collisionless system induced by an exterior perturbation is derived while assuming that the timescale correspond…
