Joint dynamical-geophysical evidence for a limit cycle in the Galilean moons
Amirhossein Bagheri, Steven Vance, Jim Fuller +5
Io, Europa, and Ganymede orbit in the Laplace mean-motion resonance, where their orbital and thermochemical evolution are strongly coupled [1-5]. Forced eccentricities sustain tida…

A Collective Trigger for Widespread Planetesimal Formation Revealed by Accretion Ages
James Bryson, Hannah Sanderson, Francis Nimmo +4
The formation of planetesimals was an integral part of the cascading series of processes that built the terrestrial planets. To illuminate planetesimal formation, here we develop a…

Thermal-orbital evolution of Eris
Ryunosuke Akiba, Francis Nimmo
The large Kuiper Belt object (KBO) Eris is nearly as big as Pluto and has a small moon, Dysnomia. Constraints on the system's spin and orbit characteristics were recently used to a…
