Effect of stratified turbulence on magnetic flux concentrations Academic Article uri icon


  • ABSTRACT According to conventional view, sunspots form when coherent magnetic flux tubes intersect the surface. Such tubes would rise from the bottom of the convection zone as a result of an instability. In this study an alternative view is advanced where the field is produced throughout the entire convection zone and sunspots may form from local flux concentrations near the surface. In order to understand the basic mechanism of the formation of magnetic flux concentrations, we determine by direct numerical simulations …
