Dynamical Friction for Compound Bodies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1997
In the framework of the fluctuation-dissipation approach to dynamical friction, we derive an expression giving the orbital energy exchange experienced by a compound body as it moves interacting with a non homogeneous discrete background.

Dynamical friction on satellite galaxies [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2005
For a rigid model satellite, Chandrasekhar's dynamical friction formula describes the orbital evolution quite accurately, when the Coulomb logarithm is chosen appropriately.

Dynamical friction in gravitational atoms [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2023
AbstractDue to superradiant instabilities, clouds of ultralight bosons can spontaneously grow around rotating black holes, creating so-called “gravitational atoms”. In this work, we study their dynamical effects on binary systems. We first focus on open orbits, showing that the presence of a cloud can increase the cross section for the dynamical ...

DYNAMICAL FRICTION IN CUSPY GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2014
In this paper we treat the problem of the dynamical friction decay of a massive object moving in an elliptical galaxy with a cuspidal inner distribution of the mass density. We present results obtained by both self-consistent, direct summation, N-body simulations, as well as by a new semi-analytical treatment of dynamical friction valid in such cuspy ...

DYNAMICAL FRICTION IN CUSPIDAL GALAXIES [PDF]

open access: yesThe Thirteenth Marcel Grossmann Meeting, 2015
Dynamical friction is the process responsible for matter transport toward the inner regions of galaxies in form of massive objects, like intermediate mass black holes, globular clusters and small satellite galaxies. While very bright galaxies show an almost flat luminosity profile in the inner region, fainter ones have, usually, a peaked, cuspidal ...

Taking apart the dynamical clock. Fat-tailed dynamical kicks shape the blue-straggler star bimodality

open access: yes, 2020
In globular clusters, blue straggler stars are heavier than the average star, so dynamical friction strongly affects them. The radial distribution of BSS, normalized to a reference population, appears bimodal in a fraction of Galactic GCs, with a density

DYNAMICAL FRICTION IN THE LOCAL GROUP

open access: yesOdessa Astronomical Publications, 2013
In this paper we consider dynamical behavior of the astrophysical objects in the Local Group. The motion of Andromed and The Milky Way is studied. We distinguish two different models: for the first one we do not take into account the influence of the ...
