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…
The solar dynamo begins near the surface
Geoffrey M Vasil, Daniel Lecoanet, Kyle Augustson +5
The Sun's magnetic dynamo cycle features a distinct pattern: a propagating region of sunspot emergence appears around 30 degrees latitude and vanishes near the equator every 11 yea…
Iterative Methods for Navier--Stokes Inverse Problems
Liam O'Connor, Daniel Lecoanet, Evan H. Anders +5
Even when the partial differential equation underlying a physical process can be evolved forward in time, the retrospective (backward in time) inverse problem often has its own cha…
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…
How do tidal waves interact with convective vortices in rapidly-rotating planets and stars?
Virgile Dandoy, Junho Park, Kyle Augustson +2
The dissipation of tidal inertial waves in planetary and stellar convective regions is one of the key mechanisms that drive the evolution of star-planet/planet-moon systems. In thi…
Powering Stellar Magnetism: Energy Transfers in Cyclic Dynamos of Sun-like Stars
Allan Sacha Brun, Antoine Strugarek, Quentin Noraz +5
We use the ASH code to model the convective dynamo of solar-type stars. Based on a series of 15 3-D MHD simulations spanning 4 bins in rotation and mass, we show what mechanisms ar…
