Fine-scale opposite-polarity magnetic fields in a solar plage revealed by integral field spectropolarimetry
G. Liu, I. MiliÄ, J. S. Castellanos Duran +3
Plages are small concentrations of strong, nearly vertical magnetic fields in the solar photosphere that expand with height. A high spatial and spectral resolution that can resolve…
