Evidence of Twisted Flux-Tube Emergence in Active Regions

Mostrar todas las versiones(2)

Elongated magnetic polarities are observed during the emergence phase of bipolar active regions (ARs). These extended features, called magnetic tongues, are interpreted as a consequence of the azimuthal component of the magnetic flux in the toroidal flux-tubes that form ARs. We develop a new systema...
