Scott D. Tremaine Astrophysicist

Scott Tremaine’s research is focused on the dynamics of astrophysical systems, including planet formation and evolution, comets, galaxies, and other stellar systems. He has made seminal contributions to understanding the formation and evolution of planetary systems, comets, black holes, star clusters, galaxies, and galaxy systems. He predicted the Kuiper belt of comets beyond Neptune and, with colleague Peter Goldreich, the existence of shepherd satellites and density waves in Saturn’s ring system, as well as the phenomenon of planetary migration. He interpreted double-nuclei galaxies, such as the nearby Andromeda galaxy, as eccentric stellar disks, and elucidated the role of dynamical friction in galaxy evolution.
