Unveiling What Makes Saturn Ring: Quantifying the Amplitudes of Saturn's Planetary Normal-Mode Oscillations and Trends in C-Ring Properties Using Kronoseismology (VII)
Victor M Afigbo, Matthew M Hedman, Phillip Nicholson +4
Certain spiral density waves in Saturn's rings are generated through resonances with planetary normal modes, making them valuable probes of Saturn's internal structure. Previous re…
Saturn's Interior After the Cassini Grand Finale
J. J. Fortney, B. Militzer, C. R. Mankovich +8
We present a review of Saturn's interior structure and thermal evolution, with a particular focus on work in the past 5 years. Data from the Cassini mission, including a precise de…
Saturn's Seismic Rotation Revisited
Christopher R. Mankovich, Janosz W. Dewberry, Jim Fuller
Normal mode seismology is a promising means of measuring rotation in gas giant interiors, and ring seismology presents a singular opportunity to do so at Saturn. We calculate Satur…
Impacts of zonal winds on planetary oscillations and Saturn ring seismology
Janosz W. Dewberry, Christopher R. Mankovich, Jim Fuller
The excitation of density and bending waves in Saturn's C ring by planetary oscillation modes presents a unique opportunity to learn about gas giant interiors and rotation. However…
Ring Seismology of the Ice Giants Uranus and Neptune
Joseph A. A'Hearn, Matthew M. Hedman, Christopher R. Mankovich +2
We assess the prospect of using ring seismology to probe the interiors of the ice giants Uranus and Neptune. We do this by calculating normal mode spectra for different interior mo…
Theory of Figures to the 7th order and the interiors of Jupiter and Saturn
N. Nettelmann, N. Movshovitz, D. Ni +6
Interior modeling of Jupiter and Saturn has advanced to a state where thousands of models are generated that cover the uncertainty space of many parameters. This approach demands a…
Constraining Saturn's interior with ring seismology: effects of differential rotation and stable stratification
Janosz W. Dewberry, Christopher R. Mankovich, Jim Fuller +2
Normal mode oscillations in Saturn excite density and bending waves in the C Ring, providing a valuable window into the planet's interior. Saturn's fundamental modes (f modes) exci…
A diffuse core in Saturn revealed by ring seismology
Christopher Mankovich, Jim Fuller
The best constraints on the internal structures of giant planets have historically come from measurements of their gravity fields. These gravity data are inherently mostly sensitiv…
Saturn's rings as a seismograph to probe Saturn's internal structure
Christopher R. Mankovich
As it has already done for Earth, the sun, and the stars, seismology has the potential to radically change the way the interiors of giant planets are studied. In a sequence of even…
Evidence for a Dichotomy in the Interior Structures of Jupiter and Saturn from Helium Phase Separation
Christopher R. Mankovich, Jonathan J. Fortney
We examine the comparative thermal evolution of Jupiter and Saturn applying recent theoretical results for helium's immiscibility in fluid metallic hydrogen. The redistribution of…
Saturn's Probable Interior: An Exploration of Saturn's Potential Interior Density Structures
Naor Movshovitz, Jonathan J. Fortney, Chris Mankovich +2
The gravity field of a giant planet is typically our best window into its interior structure and composition. Through comparison of a model planet's calculated gravitational potent…
Cassini Ring Seismology as a Probe of Saturn's Interior I: Rigid Rotation
Christopher Mankovich, Mark S. Marley, Jonathan J. Fortney +1
Seismology of the gas giants holds the potential to resolve long-standing questions about their internal structure and rotation state. We construct a family of Saturn interior mode…
Double-diffusive erosion of the core of Jupiter
R. Moll, P. Garaud, C. Mankovich +1
We present Direct Numerical Simulations of the transport of heat and heavy elements across a double-diffusive interface or a double-diffusive staircase, in conditions that are clos…
Bayesian Evolution Models for Jupiter with Helium Rain and Double-diffusive Convection
Christopher Mankovich, Jonathan J. Fortney, Kevin L. Moore
Hydrogen and helium demix when sufficiently cool, and this bears on the evolution of all giant planets at large separations at or below roughly a Jupiter mass. We model the thermal…
Excitation of gravity waves by fingering convection, and the formation of compositional staircases in stellar interiors
P. Garaud, M. Medrano, J. Brown +2
Fingering convection (or thermohaline convection) is a weak yet important kind of mixing that occurs in stably-stratified stellar radiation zones in the presence of an inverse mean…
An Exploration of Double Diffusive Convection in Jupiter as a Result of Hydrogen-Helium Phase Separation
N. Nettelmann, J. J. Fortney, K. Moore +1
Jupiter's atmosphere has been observed to be depleted in helium (Yatm~0.24), suggesting active helium sedimentation in the interior. This is accounted for in standard Jupiter struc…
Angular momentum transport within evolved low-mass stars
Matteo Cantiello, Christopher Mankovich, Lars Bildsten +2
Asteroseismology of 1.0-2.0 Msun red giants by the Kepler satellite has enabled the first definitive measurements of interior rotation in both first ascent red giant branch (RGB) s…
Modules for Experiments in Stellar Astrophysics (MESA): Giant Planets, Oscillations, Rotation, and Massive Stars
Bill Paxton, Matteo Cantiello, Phil Arras +8
We substantially update the capabilities of the open source software package Modules for Experiments in Stellar Astrophysics (MESA), and its one-dimensional stellar evolution modul…
