In the current literature two types of explanations can be found. The first one is related to the buoyant emergence of toroidal magnetic fields generated at the tachocline. The second one states that active regions are formed, from initially diffused magnetic flux, by MHD instabilities that develop in the near-surface layers of the Sun. Using the anelastic MHD code EULAG we address the problem of sunspot formation by performing implicit large-eddy simulations of stratified magneto-convection in a domain that resembles the near-surface layers of the Sun. The development of magnetic structures is explored as well as their effect on the convection dynamics. By applying a homogeneous magnetic field over an initially stationary hydrodynamic convective state, we investigate the formation of self-organized magnetic structures in the range of the initial magnetic field strength, 0.01 < B0/Beq < 0.5, where Beq is the characteristic equipartition field strength.engUniversidade Federal de Minas GeraisUFMGBrasilICX - DEPARTAMENTO DE FÍSICAProceedings of the International Astronomical UnionSolCampos magnéticosConvectionTurbulenceSunspotsImplicit Large-eddy simulationsExploring shallow sunspot formation by using Implicit Large-eddy simulationsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/exploring-shallow-sunspot-formation-by-using-implicit-largeeddy-simulations/5F8A71882BAF15BF198D396642682DE7Francisco Javier Camacho RodriguezGustavo Andres Guerrero ErasoPiotr Krzysztof SmolarkiewiczAlexander G.
