Magnetic Flux Transport by turbulent reconnection in astrophysical flows
Elisabete M. de Gouveia Dal Pino, Márcia R. M. Leão, Reinaldo Santos-Lima +3
The role of MHD turbulence in astrophysical environments is still highly debated. An important question that permeates this debate is the transport of magnetic flux. This is partic…
Dynamo action and magnetic buoyancy in convection simulations with vertical shear
G. Guerrero, P. Käpylä
A hypothesis for sunspot formation is the buoyant emergence of magnetic flux tubes created by the strong radial shear at the tachocline. In this scenario, the magnetic field has to…
The role of diffusivity quenching in flux-transport dynamo models
G. A. Guerrero, M. Dikpati, E. M. de Gouveia Dal Pino
In the non-linear phase of a dynamo process, the back-reaction of the magnetic field upon the turbulent motion results in a decrease of the turbulence level and therefore in a supp…
