DKIST Unveils Four-Lobed Stokes U Profiles in a Magnetically Complex Sunspot Penumbra
Ryan James Campbell, Sarah Jaeggli
We present DKIST spectropolarimetric observations of a sunspot penumbra revealing spatially coherent four-lobed Stokes U profiles that persist after polarimetric crosstalk correcti…

Magnetic diffusion in Solar atmosphere produces measurable electric fields
Tetsu Anan, Roberto Casini, Han Uitenbroek +13
The efficient release of magnetic energy in astrophysical plasmas, such as during solar flares, can in principle be achieved through magnetic diffusion, at a rate determined by the…
