Tidal dissipation in giant planets

J Fuller, T Guillot, S Mathis, C Murray - Space Science Reviews, 2024 - Springer
Tidal interactions between moons and planets can have major effects on the orbits, spins,

Dwindling Surface Cooling of a Rotating Jovian Planet Leads to a Convection Zone That Grows to a Finite Depth

BW Hindman, JR Fuentes - The Astrophysical Journal Letters, 2023 - iopscience.iop.org
Recent measurements of Jupiter's gravitational field (by Juno) and seismology of Saturn's
rings (by Cassini) strongly suggest that both planets have a stably stratified core that still …

Convective mixing in distant and close-in giant planets-Dependences on the initial composition, luminosity, bloating, and semi-convection

J Polman, C Mordasini - Astronomy & Astrophysics, 2024 - aanda.org
Recent structure models of Jupiter suggest the existence of an extended region in the deep
interior with a high heavy element abundance, referred to as a dilute core. This finding has …

Convective mixing in gas giant planets with primordial composition gradients

H Knierim, R Helled - The Astrophysical Journal, 2024 - iopscience.iop.org
Linking atmospheric measurements to the bulk planetary composition and ultimately the
planetary origin is a key objective in planetary science. In this work, we identify the cases in …
