Magnetic Buoyancy and Rotational Instabilities in the Tachocline

Instability domains in low and middle latitudes
Wednesday, January 17, 2018

Peter Gilman presents results from an analytical model for magnetic buoyancy and ro­tational instabilities in a full spherical shell tachocline that includes rotation. differential rotation close to that observed helioseismicly, and toroidal field.

Babcock-Leighton Solar Dynamo: The Role of Downward Pumping and the Equatorward Propagation of Activity

Snapshots of poloidal field
Monday, October 10, 2016

The key elements of the Babcock-Leighton dynamos are the generation of poloidal field through decay and dispersal of tilted bipolar active regions and the generation of toroidal field through the observed differential rotation.

MHD Simulation of Flux Tube

A simulation with the FSAM code of the buoyant rise of an initially untwisted, uniformly buoyant toroidal flux tube.
