Evolution of Binaries Under Stochastic Perturbations
Andrea Caputo, Giovanni Maria Tomaselli, Chris Hamilton
The paper presents a Fokker‑Planck framework for modeling how Keplerian binary systems evolve under random tidal and impulsive perturbations, providing explicit drift and diffusion…
Kinetic Theory of Stellar Systems: A Tutorial
Chris Hamilton, Jean-Baptiste Fouvry
Stellar systems - star clusters, galaxies, dark matter haloes, and so on - are ubiquitous characters in the evolutionary tale of our Universe. This tutorial article is an introduct…
Eccentricity dynamics of wide binaries -- II. The effect of stellar encounters and constraints on formation channels
Chris Hamilton, Shaunak Modak
GAIA wide stellar binaries (separations AU) are observed to have a superthermal eccentricity distribution function (DF), well-fit by with $…
Binary mergers in the centers of galaxies: synergy between stellar flybys and tidal fields
Mila Winter-Granic, Cristobal Petrovich, ValentÃn Peña-Donaire +1
Galactic centers are very dynamically active environments, often harbouring a nuclear star cluster and supermassive black hole at their cores. Binaries in these environments are su…
Saturation of spiral instabilities in disk galaxies
Chris Hamilton
Spiral density waves can arise in galactic disks as linear instabilities of the underlying stellar distribution function. Such an instability grows exponentially in amplitude at so…
