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,
and thermal evolution of the moons. In the Saturn system, tidal dissipation in the planet …

Rotation reduces convective mixing in Jupiter and other gas giants

JR Fuentes, EH Anders, A Cumming… - The Astrophysical …, 2023 - iopscience.iop.org
Recent measurements of Jupiter's gravitational moments by the Juno spacecraft and
seismology of Saturn's rings suggest that the primordial composition gradients in the deep …

Can Jupiter's Atmospheric Metallicity Be Different from the Deep Interior?

S Müller, R Helled - The Astrophysical Journal, 2024 - iopscience.iop.org
Updated formation and structure models of Jupiter predict a metal-poor envelope. This is at
odds with the two to three times solar metallicity measured by the Galileo probe …

Evolution of Semiconvective Staircases in Rotating Flows: Consequences for Fuzzy Cores in Giant Planets

JR Fuentes, BW Hindman, AE Fraser… - The Astrophysical …, 2024 - iopscience.iop.org
Recent observational constraints on the internal structure of Jupiter and Saturn suggest that
these planets have" fuzzy" cores, ie, gradients of the concentration of heavy elements that …

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 …

The interior of Uranus-Thermal profile, bulk composition, and the distribution of rock, water, and hydrogen and helium

L Morf, S Müller, R Helled - Astronomy & Astrophysics, 2024 - aanda.org
We present improved empirical density profiles of Uranus and interpret them in terms of their
temperature and composition using a new random algorithm. The algorithm to determine the …

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 …

Stochastic excitation of waves in magnetic stars-I. Scaling laws for the mode amplitudes

L Bessila, S Mathis - Astronomy & Astrophysics, 2024 - aanda.org
Context. Stellar oscillations are key to unravelling stellar properties, such as their mass,
radius, and age. This in turn enables us to date and characterize their exoplanetary systems …

Stable stratification of the helium rain layer yields vastly different interiors and magnetic fields for Jupiter and Saturn

S Markham, T Guillot - The Planetary Science Journal, 2024 - iopscience.iop.org
At sufficiently high pressures (∼ Mbar) and low temperatures (∼ 10 3–10 4 K), hydrogen
and helium become partly immiscible. Interpretations of Jupiter's and Saturn's magnetic …
