Dynamical von Zeipel-Lidov-Kozai Oscillations of a Binary on a Spherical Orbit around a Rotating Supermassive Black Hole
Kei-ichi Maeda, Hirotada Okawa
We study the dynamics of a binary system orbiting a rotating supermassive black hole (SMBH). Using Fermi-Walker transport, we construct a local inertial reference frame in the Kerr…

Einstein Cluster as Central Spiky Distribution of Galactic Dark Matter
Kei-ichi Maeda, Vitor Cardoso, Anzhong Wang
Using the Einstein cluster models, we construct a fully relativistic, spherically symmetric, spiky structure of matter distribution near a supermassive black hole. We introduce and…
