Dynamical dissolution of soft primordial binaries fully explains observed main-sequence binary fractions in globular clusters under solar-neighborhood initial conditions.
An intermediate-mass companion to Sgr A* plus resonant relaxation in a depleting gas disk can simultaneously produce the observed orbits of S-stars, clockwise disk stars, and off-disk stars within their 6-15 Myr lifetimes.

The complex kinematics of the young stars orbiting the supermassive black hole in the Galactic center can be explained by the presence of an intermediate mass companion of Sgr A$^\star$
An intermediate-mass companion to Sgr A* plus resonant relaxation in a depleting gas disk can simultaneously produce the observed orbits of S-stars, clockwise disk stars, and off-disk stars within their 6-15 Myr lifetimes.
