On the dynamics of overshooting convection in spherical shells: effect of density stratification and rotation

L Korre, NA Featherstone - The Astrophysical Journal, 2021 - iopscience.iop.org
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 mixing …

Dynamics of the solar tachocline–III. Numerical solutions of the Gough and McIntyre model

LA Acevedo-Arreguin, P Garaud… - Monthly Notices of the …, 2013 - academic.oup.com
We present the first numerical simulations of the solar interior to exhibit a tachocline
consistent with the Gough and McIntyre model. We find non-linear, axisymmetric, steady …

A self-consistent model of the solar tachocline

TS Wood, NH Brummell - The Astrophysical Journal, 2018 - iopscience.iop.org
We present a local but fully nonlinear model of the solar tachocline, using three-dimensional
direct numerical simulations. The tachocline forms naturally as a statistically steady balance …
