Abstract We use the numerical model of R. Malhotra (1991, Icarus 94, 399–412) to explore the orbital history of Io, Europa, and Ganymede for a large range of parameters and initial conditions near the Laplace resonance. We identify two new Laplace-like resonances which pump Ganymede's eccentricity and may help explain the resurfacing of Ganymede. Near the Laplace resonance, the Io–Europa conjunction drifts at a mean angular velocity ω 1 ≡ 2 n 2 − n 1 , while the Europa-Ganymede conjunction… Expand

Coupled Orbital and Thermal Evolution of Ganymede
We explore the hypothesis that passage through an eccentricity-pumping resonance could lead to the resurfacing of Ganymede. To do so, we couple R. Malhotra's (1991, Icarus 94, 399–412) orbital modelExpand
The dynamics of Laplace-like resonances.
TLDR
In several cases, the standard Laplace resonance of the Galilean satellites displays a regular behavior in comparison to other resonances characterized by different mean longitude ratios, which instead show a rather chaotic behavior even on short time scales. Expand
The orbital–thermal evolution and global expansion of Ganymede
Article history: The tectonically and cryovolcanically resurfaced terrains of Ganymede attest to the satellite's turbulent geologic history. Yet, the ultimate cause of its geologic violence remainsExpand
Element history of the Laplace resonance: a dynamical approach
We consider the three-body mean motion resonance defined by the Jovian moons Io, Europa, and Ganymede, which is commonly known as the Laplace resonance. In particular, we construct approximate modelsExpand
Thermal-orbital evolution of Io and Europa
Coupled thermal-orbital evolution models of Europa and Io are presented. It is assumed that Io, Europa, and Ganymede evolve in the Laplace resonance and that tidal dissipation of orbital energy is anExpand
THE ROLE OF SECONDARY RESONANCES IN THE EVOLUTION OF THE MIMAS-TETHYS SYSTEM
Abstract We have numerically investigated the role of the 200-year-long period, recently discovered, on the past tidal evolution of the Mimas–Tethys system through the present inclination-typeExpand
Tidally Heated Terrestrial Exoplanets: Viscoelastic Response Models
Tidal friction in exoplanet systems, driven by orbits that allow for durable nonzero eccentricities at short heliocentric periods, can generate internal heating far in excess of the conditionsExpand
The production of Ganymede's magnetic field
Abstract One of the great discoveries of NASA's Galileo mission was the presence of an intrinsically produced magnetic field at Ganymede. Generation of the relatively strong (750 nT) field likelyExpand
Tidal dissipation within large icy satellites: Applications to Europa and Titan
This paper describes a new approach based on variational principles to calculate the radial distribution of tidal energy dissipation in any satellite. The advantage of the model with respect toExpand
Tidally Induced Volcanism
The dissipation of tidal energy causes the ongoing silicate volcanism on Jupiter's satellite, Io, and cryovolcanism almost certainly has resurfaced parts of Saturn's satellite, Enceladus, at variousExpand

Tidal origin of the Laplace resonance and the resurfacing of Ganymede
Abstract I present a new scenario for the tidal origin of the Laplace resonance. The inner three Galilean satellites are supposed to have formed in orbits well away from the 2/1 pair-wise mean motionExpand

The tides of Io
Abstract The Galilean satellites Io, Europa, and Ganymede interact through several stable orbital resonances where λ 1 − 2λ 2 + ω 1 = 0, λ 1 − 2λ 2 + ω 2 = 180°, λ 2 − 2λ 3 + ω 2 = 0 and λ1 − 3λ2 +Expand

The orbital motions of the Galilean satellites exert dramatic control over their physical properties (most notably Io's) through tidal heating. In turn, tidal dissipation in the satellites, as wellExpand
