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…
Hybrid Adaptive Ray-Moment Method (HARM): A Highly Parallel Method for Radiation Hydrodynamics on Adaptive Grids
Anna L. Rosen, Mark R. Krumholz, Jeffrey S. Oishi +2
We present a highly-parallel multi-frequency hybrid radiation hydrodynamics algorithm that combines a spatially-adaptive long characteristics method for the radiation field from po…
Conduction in low Mach number flows: Part I Linear & weakly nonlinear regimes
Daniel Lecoanet, Benjamin P. Brown, Ellen G. Zweibel +3
Thermal conduction is an important energy transfer and damping mechanism in astrophysical flows. Fourier's law - the heat flux is proportional to the negative temperature gradient,…
Radial Stresses and Energy Transport in Accretion Disks
Alexander Hubbard, Colin P. McNally, Jeffrey S. Oishi +2
Early in the study of viscous accretion disks it was realized that energy transfers from distant sources must be important, not least because the flow at the disk midplane in the b…
