Long-Term Stability of Tightly Packed Multi-Planet Systems in Prograde, Coplanar, Circumstellar Orbits within the α Centauri AB System
We perform long-term simulations, up to ten billion years, of closely-spaced configurations of 2 — 6 planets, each as massive as the Earth, traveling on nested orbits about either stellar […]
