The linear response of stellar systems does not diverge at marginal stability
Chris Hamilton, Tobias Heinemann
The linear response of a stellar system's gravitational potential to a perturbing mass comprises two distinct contributions. Most famously, the system will respond by forming a pol…
Wide binary stars formed in the turbulent interstellar medium
Siyao Xu, Hsiang-Chih Hwang, Chris Hamilton +1
The ubiquitous interstellar turbulence regulates star formation and the scaling relations between the initial velocity differences and the initial separations of stars. We propose…
On the radial velocity wave in the Galactic disk
Chris Hamilton, Andrew Mummery, Joss Bland-Hawthorn
Stars in the Galactic disk have mean radial velocities that oscillate as a function of angular momentum . This `- wave' signal also e…
Relativistic phase space diffusion of compact object binaries in stellar clusters and hierarchical triples
Chris Hamilton, Roman R. Rafikov
The LIGO/Virgo detections of compact object mergers have posed a challenge for theories of binary evolution and coalescence. One promising avenue for producing mergers dynamically…
Secular dynamics of binaries in stellar clusters I: general formulation and dependence on cluster potential
Chris Hamilton, Roman R. Rafikov
Orbital evolution of binary systems in dense stellar clusters is important in a variety of contexts: origin of blue stragglers, progenitors of compact object mergers, millisecond p…
On the maximum disk heating attributable to fuzzy dark matter
Chris Hamilton
Fuzzy dark matter (FDM) granulations would drive orbital transport of stars in galactic disks, and in particular would produce roughly equal amounts of radial heating and radial mi…
