A Coordinate System for Dynamical Instabilities in Hierarchical Systems in REBOUND
Tiger Lu, Garett Brown
We implement coordinates suitable for studying wide binary systems in TRACE, a hybrid integrator in the widely used open-source N-body integration package REBOUND. This is a regime…
On the statistical convergence of N-body simulations of the Solar System
Hanno Rein, Garett Brown, Mei Kanda
Most direct N-body integrations of planetary systems use a symplectic integrator with a fixed timestep. A large timestep is desirable in order to speed up the numerical simulations…
A substellar flyby that shaped the orbits of the giant planets
Garett Brown, Renu Malhotra, Hanno Rein
The modestly eccentric and non-coplanar orbits of the giant planets pose a challenge to solar system formation theories which generally indicate that the giant planets emerged from…
The Potential Impact of Primordial Black Holes on Exoplanet Systems
Garett Brown, Linda He, James Unwin
The orbits of planetary systems can be deformed from their initial configurations due to close encounters with larger astrophysical bodies. Typical candidates for close encounters…
