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…
Driving Solar Giant Cells through the Self-Organization of Near-Surface Plumes
Nicholas J. Nelson, Nicholas A. Featherstone, Mark S. Miesch +1
Global 3D simulations of solar giant-cell convection have provided significant insight into the processes which yield the Sun's observed differential rotation and cyclic dynamo act…
2-D and 3-D Models of Convective Turbulence and Oscillations in Intermediate-Mass Main-Sequence Stars
Joyce A. Guzik, T. H. Morgan, N. J. Nelson +5
We present multidimensional modeling of convection and oscillations in main-sequence stars somewhat more massive than the Sun, using three separate approaches: 1) Using the 3-D pla…
Generating buoyant magnetic flux ropes in solar-like convective dynamos
Nicholas J. Nelson, Mark S. Miesch
Our Sun exhibits strong convective dynamo action which results in magnetic flux bundles emerging through the stellar surface as magnetic spots. Global-scale dynamo action is believ…
Buoyant Magnetic Loops Generated by Global Convective Dynamo Action
Nicholas J. Nelson, Benjamin P. Brown, A. Sacha Brun +2
Our global 3D simulations of convection and dynamo action in a Sun-like star reveal that persistent wreaths of strong magnetism can be built within the bulk of the convention zone.…
Magnetic Wreaths and Cycles in Convective Dynamos
Nicholas J. Nelson, Benjamin P. Brown, A. Sacha Brun +2
Solar-type stars exhibit a rich variety of magnetic activity. Seeking to explore the convective origins of this activity, we have carried out a series of global 3D magnetohydrodyna…
