Simulations of magneto-convection in the solar photosphere Equations, methods, and results of the MURaM code
TL;DR: In this article, a 3D magnetohydrodynamics simulation code for applications in the solar convection zone and photosphere was developed, including a non-local and non-grey radiative transfer module and taking into account the effects of partial ionization.
Journal ArticleDOI
On the Origin of Magnetic Fields in the Quiet Photosphere
TL;DR: In this article, the authors consider the possibility that a substantial fraction of the magnetic field in the quiet photosphere is generated locally by dynamo action associated with the granular and supergranular flows.
Journal ArticleDOI
Nonlinear Restrictions on Dynamo Action
TL;DR: In this paper, it was argued that in the limit of small diffusivity only a small amount of flux, many orders of magnitude less than the observed fluxes, can be created by dynamo processes.
Journal ArticleDOI
On the interaction between convection and magnetic fields
TL;DR: In this article, large-scale, three-dimensional, numerical experiments on highly nonlinear magnetoconvection in a Boussinesq fluid show that there is a continuous transition from a dynamo regime through a convective regime to an oscillatory regime as the strength of the imposed magnetic field is progressively increased.
Journal ArticleDOI
Nonlinear saturation of the turbulent alpha effect.
Fausto Cattaneo,David W. Hughes +1 more
TL;DR: In this article, the saturation of the turbulent ε-alpha effect in the nonlinear regime was studied and the results were in close agreement with the theories that predict strong suppression and are incompatible with those that predict that the turbulent effect persists up to mean fields of order of the equipartition energy.
