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…
Dynamos in Stellar Convection Zones: of Wreaths and Cycles
Benjamin P Brown
We live near a magnetic star whose cycles of activity are driven by dynamo action beneath the surface. In the solar convection zone, rotation couples with plasma motions to build h…
Persistent Magnetic Wreaths in a Rapidly Rotating Sun
Benjamin P. Brown, Matthew K. Browning, Allen Sacha Brun +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…
Global-scale wreath-building dynamos in stellar convection zones
Benjamin P Brown, Matthew K Browning, Allan S Brun +2
When stars like our Sun are young they rotate rapidly and are very magnetically active. We explore dynamo action in rapidly rotating suns with the 3-D MHD anelastic spherical harmo…
Global magnetic cycles in rapidly rotating younger suns
Nicholas J. Nelson, Benjamin P. Brown, Matthew K. Browning +3
Observations of sun-like stars rotating faster than our current sun tend to exhibit increased magnetic activity as well as magnetic cycles spanning multiple years. Using global sim…
