Ganymede Might Still Be Forming Its Metal Core Today
Jupiter’s moon Ganymede is the largest moon in the solar system; at over 3,200 miles across, it is larger than the planet Mercury. It is also the only moon with […]

Saturn (upper right) lacks a strong magnetic field so its circumplanetary disk evolves without a cavity. Credit: Yuri I.

Callisto’s Nonresonant Orbit As An Outcome Of Circum-Jovian Disk Substructure
The Galilean moons of Io, Europa, and Ganymede exhibit a 4:2:1 commensurability in their mean motions, a configuration known as the Laplace resonance.

Not Just Gas: How Solid-Driven Torques Shaped the Migration of the Galilean Moons
The primary aim of this study is to investigate the orbital migration of the Galilean moons by incorporating self-consistent solid dynamics in circumjovian disk models. We perform two-fluid simulations using […]
