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…
On the penetration of large-scale flows into stellar radiative zones
Lydia Korre, Nicholas A. Featherstone
The propagation of meridional circulation below the base of the convection zone of low-mass stars may play a crucial role in the transport of angular momentum and also significantl…
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 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…
Can we reveal the core-chemical composition of ultra-massive white dwarfs through their magnetic fields?
Maria E. Camisassa, Roberto Raddi, Leandro G. Althaus +5
Ultra-massive white dwarfs () are particularly interesting objects that allow us to study extreme astrophysical phenomena such as type Ia superno…
On the dynamics of overshooting convection in spherical shells: Effect of density stratification and rotation
Lydia Korre, Nicholas A. Featherstone
Overshooting of turbulent motions from convective regions into adjacent stably stratified zones plays a significant role in stellar interior dynamics as this process may lead to mi…
On the dynamical interaction between overshooting convection and an underlying dipole magnetic field -- I. The non-dynamo regime
Lydia Korre, Nicholas H. Brummell, Pascale Garaud +1
Motivated by the dynamics in the deep interiors of many stars, we study the interaction between overshooting convection and the large-scale poloidal fields residing in radiative zo…
Convective dynamics with mixed temperature boundary conditions: why thermal relaxation matters and how to accelerate it
Evan H. Anders, Geoffrey M. Vasil, Benjamin P. Brown +1
Astrophysical simulations of convection frequently impose different thermal boundary conditions at the top and the bottom of the domain in an effort to more accurately model natura…
Convective overshooting and penetration in a Boussinesq spherical shell
Lydia Korre, Pascale Garaud, Nicholas Brummell
We study the dynamics associated with the extension of turbulent convective motions from a convection zone (CZ) into a stable region (RZ) that lies below the latter. For that purpo…
Weakly non-Boussinesq convection in a gaseous spherical shell
Lydia Korre, Nicholas Brummell, Pascale Garaud
We examine the dynamics associated with weakly compressible convection in a spherical shell by running 3D direct numerical simulations using the Boussinesq formalism [1]. Motivated…
