Can instrumental effects obscure the true photospheric wave spectrum?

M. Berretti, M. Stangalini, D. B. Jess +6

Optical aberrations and instrument resolution can affect the observed morphological properties of features in the solar atmosphere. However, little work has been done to study the…

First detection of acoustic-like flux in the middle solar corona

V. Andretta, L. Abbo, G. Jerse +28

Waves are thought to play a significant role in the heating of the solar atmosphere and the acceleration of the wind. Among the many types of waves observed in the Sun, the so-call…

Umbral oscillations in the photosphere. A comprehensive statistical study

M. Berretti, M. Stangalini, G. Verth +4

It is well-known that the global acoustic oscillations of the Sun's atmosphere can excite resonance modes within large-scale magnetic concentrations. These structures are conduits…

ASR: Archival Solar flaRes catalogue

M. Berretti, S. Mestici, L. Giovannelli +4

Solar flares result from the rapid conversion of stored magnetic energy within the Sun's corona. These energy releases are associated with coronal magnetic loops, which are rooted…

The dynamics of small-scale magnetic fields modulated by the solar cycle

M. Stangalini, G. Verth, V. Fedun +9

In addition to sunspots, which represent the most easily visualized manifestation of solar magnetism, cutting-edge observations of the solar atmosphere have uncovered a plethora of…

Metis Observations of Alfvénic Outflows Driven by Interchange Reconnection in a Pseudostreamer

P. Romano, P. Wyper, V. Andretta +33

This study presents observations of a large pseudostreamer solar eruption and, in particular, the post-eruption relaxation phase, as captured by Metis onboard the Solar Orbiter on…
