Global-scale Simulations of Stellar Convection and their Observational Predictions
Benjamin P. Brown
Stars on the lower main sequence (F-type through M-type) have substantial convective envelopes beneath their stellar photospheres. Convection in these regions can couple with rotat…
Magnetic Cycles in a Convective Dynamo Simulation of a Young Solar-type Star
Benjamin P. Brown, Mark S. Miesch, Matthew K. Browning +2
Young solar-type stars rotate rapidly and many are magnetically active; some undergo magnetic cycles similar to the 22-year solar activity cycle. We conduct simulations of dynamo a…
An Experimental Plasma Dynamo Program for Investigations of Fundamental Processes in Heliophysics
Benjamin Brown, Cary Forest, Mark Nornberg +3
Plasma experiments in laboratory settings offer unique opportunities to address fundamental aspects of the solar dynamo and magnetism in the solar atmosphere. We argue here that gr…
Global-scale Magnetism (and Cycles) in Dynamo Simulations of Stellar Convection Zones
Benjamin P Brown, Matthew K Browning, Allan Sacha Brun +2
Young solar-type stars rotate rapidly and are very magnetically active. The magnetic fields at their surfaces likely originate in their convective envelopes where convection and ro…
Wreathes of Magnetism in Rapidly Rotating Suns
Benjamin P. Brown, Matthew K. Browning, Mark S. Miesch +2
When our Sun was young it rotated much more rapidly than now. Observations of young, rapidly rotating stars indicate that many possess substantial magnetic activity and strong axis…
