The Unsteady Taylor--Vortex Dynamo is Fast
Liam O'Connor, Daniel Lecoanet, Geoffrey M. Vasil +6
Astrophysical and geophysical fluids commonly generate organized magnetic fields, despite having enormous magnetic Reynolds numbers and abundant small-scale turbulence. F…
Nonlinear interaction between dynamo-generated magnetic fields, mean flows and internal gravity waves in stellar stably-stratified layers: From 3D to 1D
Florentin Daniel, Ludovic Petitdemange, Charly Pinçon +3
Magnetic fields have been constrained at the surface of several massive and intermediate-mass stars, but their origin and properties in deep stellar radiative interiors are still d…
A self-consistent numerical model of internal wave-induced mean flow oscillations in polar geometry
Florentin Daniel, Daniel Lecoanet
The Earth's Quasi-Biennial Oscillation (QBO) is a natural example of wave-mean flow interaction and corresponds to the alternating directions of winds in the equatorial stratospher…
New constraint on Europa's ice shell: magnetic signature from the ocean
Florentin Daniel, Ludovic Petitdemange, Christophe Gissinger
Jupiter's icy moons are believed to host subsurface liquid oceans, and among them, Europa stands out as one of the most promising candidates for extraterrestrial life. Yet, the pro…
