Spectropolarimetric Fluctuations in a Sunspot Chromosphere
M. Stangalini, D. Baker, G. Valori +8
The instrumental advances made in this new era of 4-meter class solar telescopes with unmatched spectropolarimetric accuracy and sensitivity, will enable the study of chromospheric…
Unveiling the magnetic nature of chromospheric vortices
Mariarita Murabito, Juie Shetye, Marco Stangalini +5
Vortex structures in the Sun's chromosphere are believed to channel energy between different layers of the solar atmosphere. We investigate the nature and dynamics of two small-sca…
Restoring process of sunspot penumbra
P. Romano, M. Murabito, S. L. Guglielmino +2
We describe the disappearance of a sector of sunspot penumbra and its restoring process observed in the preceding sunspot of active region NOAA 12348. The evolution of the magnetic…
Magnetohydrodynamic Non-linearities in Sunspot Atmospheres: Chromospheric Detections of Intermediate Shocks
S. J. Houston, D. B. Jess, R. Keppens +8
The formation of shocks within the solar atmosphere remains one of the few observable signatures of energy dissipation arising from the plethora of magnetohydrodynamic waves genera…
Spectro-Polarimetric Analysis of an Umbral Filament
S. L. Guglielmino, P. Romano, B. Ruiz Cobo +2
High-resolution observations of the solar photosphere have recently revealed the presence of elongated filamentary bright structures inside sunspot umbrae. These features, which ha…
