Photospheric Signatures of Granular-scale Flux Emergence and Cancellation at the Penumbral Boundary
Photospheric Signatures Granular-scale Flux Emergence Cancellation Penumbral Boundary
2011/10/13
We studied flux emergence events of sub-granular scale in a solar active region. New Solar Telescope (NST) of Big Bear Solar Observatory made it possible to clearly observe the photospheric signature ...

Life arose on Earth sometime in the first few hundred million years after the young planet had cooled to the point that it could support water-based organisms on its surface. The early emergence of li...
Dynamo generated field emergence through recurrent plasmoid ejections
Solar and Stellar Astrophysics (astro-ph.SR)

Magnetic buoyancy is believed to drive the transport of magnetic flux tubes from the convection zone to the surface of the Sun. The magnetic fields form twisted loop-like structures in the solar atmos...
