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…
