The relationship between solar and stellar tachoclines, dynamos, and spin-down
Loren I. Matilsky, Lydia Korre, Nicholas Brummell
The solar tachocline, a thin shear layer separating the differentially rotating convective zone (CZ) from the underlying rigidly rotating radiative zone (RZ), remains a dynamical m…
A Dynamo Confinement Scenario for the Solar Tachocline and its Implications for Spin-down in the Radiative Spreading Regime
Loren I. Matilsky, Lydia Korre, Nicholas H. Brummell
At the base of the Sun's convective zone, a narrow shear layer called the tachocline separates strong latitudinal differential rotation above from nearly rigid rotation in the radi…
Dynamo Confinement of a Radiatively Spreading Solar Tachocline Revealed by Self-consistent Global Simulations
Loren I. Matilsky, Lydia Korre, Nicholas H. Brummell
The helioseismically observed solar tachocline is a thin internal boundary layer of shear that separates the rigidly-rotating solar radiative zone from the differentially-rotating…
Towards a self-consistent hydrodynamical model of the solar tachocline
P. Garaud, D. O. Gough, L. I. Matilsky
The solar tachocline is an internal boundary layer in the Sun located between the differentially-rotating convection zone and the uniformly-rotating radiative interior beneath. Spi…
Inertial Waves in a Nonlinear Simulation of the Sun's Convection Zone and Radiative Interior
Catherine C. Blume, Bradley W. Hindman, Loren I. Matilsky
Recent observations of Rossby waves and other more exotic forms of inertial oscillations in the Sun's convection zone have kindled the hope that such waves might be used as a seism…
Confinement of the Solar Tachocline by a Non-Axisymmetric Dynamo
Loren I. Matilsky, Nicholas H. Brummell, Bradley W. Hindman +1
We recently presented the first 3D numerical simulation of the solar interior for which tachocline confinement was achieved by a dynamo-generated magnetic field. In this followup 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…
The stellar thermal wind as a consequence of oblateness
Loren I. Matilsky
In many rotating fluids, the lowest-order force balance is between gravity, pressure, and rotational acceleration ('GPR' balance). Terrestrial GPR balance takes the form of geostro…
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…
Confinement of the Solar Tachocline by Dynamo Action in the Radiative Interior
Loren I. Matilsky, Bradley W. Hindman, Nicholas A. Featherstone +2
A major outstanding problem in solar physics is the confinement of the solar tachocline, the thin shear layer that separates nearly solid-body rotation in the radiative interior fr…
Constraining Global Solar Models through Helioseismic Analysis
Andrey M. Stejko, Alexander G. Kosovichev, Nicholas A. Featherstone +4
Global hydrodynamic simulations of internal solar dynamics have focused on replicating the conditions for solar-like differential rotation and meridional circulation using the resu…
Building and Maintaining a Solar Tachocline through Convective Dynamo Action
Loren I. Matilsky, Juri Toomre
For more than thirty years, the dynamical maintenance of the thin solar tachocline has remained one of the central outstanding problems of stellar astrophysics. Three main theories…
Revisiting the Sun's Strong Differential Rotation along Radial Lines
Loren I. Matilsky, Bradley W. Hindman, Juri Toomre
Current state-of-the-art models of the solar convection zone consist of solutions to the Navier-Stokes equations in rotating, 3D spherical shells. Such models are highly sensitive…
Exploring Bistability in the Cycles of the Solar Dynamo through Global Simulations
Loren Matilsky, Juri Toomre
The calling card of solar magnetism is the sunspot cycle, during which sunspots regularly reverse their polarity sense every 11 years. However, a number of more complicated time-de…
Exploring the Influence of Density Contrast on Solar Near-Surface Shear
Loren I. Matilsky, Bradley W. Hindman, Juri Toomre
The advent of helioseismology has determined in detail the average rotation rate of the Sun as a function of radius and latitude. These data immediately reveal two striking boundar…
The Role of Downflows in Establishing Solar Near-Surface Shear
Loren I. Matilsky, Bradley W. Hindman, J. Toomre
The dynamical origins of the Sun's tachocline and near-surface shear layer (NSSL) are still not well understood. We have attempted to self-consistently reproduce a NSSL in numerica…
