Vector Resonant Relaxation of Stars around a Massive Black Hole
Jean-Baptiste Fouvry, Ben Bar-Or, Pierre-Henri Chavanis
In the vicinity of a massive black hole, stars move on precessing Keplerian orbits. The mutual stochastic gravitational torques between the stellar orbits drive a rapid reorientati…
Secular dynamics of long-range interacting particles on a sphere in the axisymmetric limit
Jean-Baptiste Fouvry, Ben Bar-Or, Pierre-Henri Chavanis
We investigate the secular dynamics of long-range interacting particles moving on a sphere, in the limit of an axisymmetric mean field potential. We show that this system can be de…
Relaxation in a Fuzzy Dark Matter Halo
Ben Bar-Or, Jean-Baptiste Fouvry, Scott Tremaine
Dark matter may be composed of light bosons, , with a de Broglie wavelength in typical galactic potentials. Such `fuzzy'…
The impact of vector resonant relaxation on the evolution of binaries near a massive black hole: implications for gravitational wave sources
Adrian S. Hamers, Ben Bar-Or, Cristobal Petrovich +1
Binaries within the sphere of influence of a massive black hole (MBH) in galactic nuclei are susceptible to the Lidov-Kozai (LK) mechanism, which can drive orbits to high eccentric…
Scalar Resonant Relaxation of Stars Around a Massive Black Hole
Ben Bar-Or, Jean-Baptiste Fouvry
In nuclear star clusters, the potential is governed by the central massive black hole, so that stars move on nearly Keplerian orbits and the total potential is almost stationary in…
