Self-Consistent Evolution Models Show Weak Double-Diffusive Mixing in Jupiter and Saturn
J. R. Fuentes, Ankan Sur, David J. Stevenson +1
Double-diffusive convection in the ``fuzzy'' cores of giant planets has been widely discussed as a mechanism for redistributing heavy elements, but its efficiency in evolutionary m…
3D Simulations of Convective Entrainment in Gas Giants: Rotation and Decreasing Luminosity as Barriers to Mixing
Shu Zhang, J. R. Fuentes, Andrew Cumming
Observations from Juno and Cassini suggest that Jupiter and Saturn may possess fuzzy cores -- central regions where the abundance of heavy elements varies smoothly with depth. Such…
Diffusive Braking of Penetrative Convection in Stably-Stratified Fluids
Bradley W. Hindman, J. R. Fuentes
Mixing at the interface between a convection zone and an adjacent, stably-stratified layer plays a crucial role in shaping the structure and evolution of stars and planets. In this…
An Energy Perspective of Core Erosion in Gas Giant Planets
J. R. Fuentes, Christopher R. Mankovich, Ankan Sur
Juno and Cassini have shown that Jupiter and Saturn likely contain extended gradients of heavy elements. Yet, how these gradients can survive over billions of years remains an open…
3D Simulations of Semiconvection in Spheres: Turbulent Mixing and Layer Formation
J. R. Fuentes
Semiconvection occurs in regions of stars and planets that are unstable to overturning convection according to the Schwarzschild criterion, yet stable according to the Ledoux crite…
Evolution of Semi-convective Staircases in Rotating Flows: Consequences for Fuzzy Cores in Giant Planets
J. R. Fuentes, Bradley W. Hindman, Adrian E. Fraser +1
Recent observational constraints on the internal structure of Jupiter and Saturn suggest that these planets have ``fuzzy" cores, i.e., gradients of the concentration of heavy eleme…
Dwindling Surface Cooling of a Rotating Jovian Planet Leads to a Convection Zone that Grows to a Finite Depth
Bradley W. Hindman, J. R. Fuentes
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 s…
Assessing the Observability of Deep Meridional Flow Cells in the Solar Interior
J. R. Fuentes, Bradley W. Hindman, Junwei Zhao +6
Meridional circulation regulates the Sun's interior dynamics and magnetism. While it is well accepted that meridional flows are poleward at the Sun's surface, helioseismic observat…
Rotation reduces convective mixing in Jupiter and other gas giants
J. R. Fuentes, Evan H. Anders, Andrew Cumming +1
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 interio…
The Puzzling Structure of Solar Convection: Window into the Dynamo
Nicholas A. Featherstone, Kyle C. Augustson, Jonathan M. Aurnou +25
The operation of the solar dynamo, with all of its remarkable spatio-temporal ordering, remains an outstanding problem of modern solar physics. A number of mechanisms that might pl…
Heat transport and convective velocities in compositionally-driven convection in neutron star and white dwarf interiors
J. R. Fuentes, A. Cumming, M. Castro-Tapia +1
We investigate heat transport associated with compositionally-driven convection driven by crystallization at the ocean-crust interface in accreting neutron stars, or growth of the…
Establishing Dust Rings and Forming Planets Within Them
Eve J. Lee, J. R. Fuentes, Philip F. Hopkins
Radio images of protoplanetary disks demonstrate that dust grains tend to organize themselves into rings. These rings may be a consequence of dust trapping within gas pressure maxi…
Layer formation in a stably-stratified fluid cooled from above. Towards an analog for Jupiter and other gas giants
J. R. Fuentes, A. Cumming, E. H. Anders
In 1D evolution models of gas giant planets, an outer convection zone advances into the interior as the surface cools, and multiple convective layers form beneath that convective f…
Schwarzschild and Ledoux are equivalent on evolutionary timescales
Evan H. Anders, Adam S. Jermyn, Daniel Lecoanet +4
Stellar evolution models calculate convective boundaries using either the Schwarzschild or Ledoux criterion, but confusion remains regarding which criterion to use. Here we present…
