Equivalence between simple multilayered and homogeneous laboratory-based rheological models in planetary science
Yeva Gevorgyan, Isamu Matsuyama, Clodoaldo Ragazzo
The goal of this work is to investigate under which circumstances the tidal response of a stratified body can be approximated by that of a homogeneous body. We show that any multil…
The thermal-orbital evolution of the Earth-Moon system with a subsurface magma ocean and fossil figure
Brynna G. Downey, Francis Nimmo, Isamu Matsuyama
Various theories have been proposed to explain the Moon's current inclined orbit. We test the viability of these theories by reconstructing the thermal-orbital history of the Moon.…
New Constraints on Pluto's Sputnik Planitia Ice Sheet from a Coupled Reorientation-Climate Model
Perianne E. Johnson, James T. Keane, Leslie A. Young +1
We present a coupled reorientation and climate model, to understand how true polar wander (TPW) and atmospheric condensation worked together to create the Sputnik Planitia (SP) ice…
Inclination damping on Callisto
Brynna G. Downey, Francis Nimmo, Isamu Matsuyama
Callisto is thought to possess a subsurface ocean, which will dissipate energy due to obliquity tides. This dissipation should have damped any primordial inclination within 1 Gyr -…
Powering the Galilean Satellites with Moon-Moon Tides
Hamish C. F. C. Hay, Antony Trinh, Isamu Matsuyama
There is compelling evidence for subsurface water oceans among the three outer Galilean satellites, and evidence for an internal magma ocean in the innermost moon, Io. Tidal forces…
Tides between the TRAPPIST-1 planets
Hamish Hay, Isamu Matsuyama
The TRAPPIST-1 system is sufficiently closely packed that tides raised by one planet on another are significant. We investigate whether this source of tidal heating is comparable t…
