| « Stellar Dynamics in Galactic Nuclei » |
|
Sofia Flores |
| The stars of the Galactic Center follow quasi-Keplerian precessing orbits around the supermassive black hole Sgr A*. These stars exhibit diffusion in their orbital plane orientation, resulting from coherent torques between the stellar orbits. This diffusion process is known as Vector Resonant Relaxation. By studying such Hamiltonian dynamics, I derive the evolution equation for the correlation of the potential fluctuations in the system, and I address the closure problem underlying its structure by adopting a generalized statistical closure scheme. I finally compare the numerical predictions of the approximation with measurements obtained from N-body simulations of the system. |
