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…
Penumbral brightening events observed in AR NOAA 12546
M. Murabito, S. L. Guglielmino, I. Ermolli +2
Penumbral transient brightening events have been attributed to magnetic reconnection episodes occurring in the low corona. We investigated the trigger mechanism of these events in…
Continuum enhancements, line profiles and magnetic field evolution during consecutive flares
Francesca Zuccarello, Salvo L. Guglielmino, Vincenzo Capparelli +5
During solar flares, magnetic energy can be converted into electromagnetic radiation from radio waves to rays. Enhancements in the continuum at visible wavelengths give rise to…
