"Collective Gravity: from Icy Planetesimals in our Solar System to Stars in Orbit About Supermassive Black Holes"

Abstract:

The collective gravity of bodies on eccentric orbits is key to understanding the evolution of planetary systems and stars near supermassive black holes. In this talk I will demonstrate the wide- ranging implications of these dynamics such as the orbital clustering of icy bodies in the outer Solar System (observations of which have motivated the Planet 9 hypothesis) and the feeding of stars and gas to supermassive black holes.
