Three-Dimensional Simulations of Solar and Stellar Dynamos: The Influence of a Tachocline
M. S. Miesch, M. K. Browning, A. S. Brun +2
We review recent advances in modeling global-scale convection and dynamo processes with the Anelastic Spherical Harmonic (ASH) code. In particular, we have recently achieved the fi…
Rapidly Rotating Suns and Active Nests of Convection
Benjamin P. Brown, Matthew K. Browning, Allan Sacha Brun +2
In the solar convection zone, rotation couples with intensely turbulent convection to drive a strong differential rotation and achieve complex magnetic dynamo action. Our sun must…
Strong Dynamo Action in Rapidly Rotating Suns
Benjamin P. Brown, Matthew K. Browning, Allan Sacha Brun +3
Stellar dynamos are driven by complex couplings between rotation and turbulent convection, which drive global-scale flows and build and rebuild stellar magnetic fields. When stars…
Rapid Rotation, Active Nests of Convection and Global-scale Flows in Solar-like Stars
Benjamin P. Brown, Matthew K. Browning, Allan Sacha Brun +2
In the solar convection zone, rotation couples with intensely turbulent convection to build global-scale flows of differential rotation and meridional circulation. Our sun must hav…
Simulations of dynamo action in fully convective stars
Matthew Browning
We present three-dimensional nonlinear magnetohydrodynamic simulations of the interiors of fully convective M-dwarfs. Our models consider 0.3 solar-mass stars using the Anelastic S…
Dynamo Action in Fully Convective Low-Mass Stars
Matthew Browning, Gibor Basri
Recent observations indicate that fully convective stars can effectively build magnetic fields without the aid of a tachocline of shear, that those fields can possess large-scale c…
