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…

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…

SoFT: Detecting and Tracking Magnetic Structures in the Solar Photosphere

M. Berretti, M. Stangalini, S. Mestici +3

In this work, we present SoFT: Solar Feature Tracking, a novel feature-tracking tool developed in Python and designed to detect, identify, and track magnetic elements in the solar…

Unexpected frequency of horizontal oscillations of magnetic structures in the solar photosphere

M. Berretti, M. Stangalini, G. Verth +6

It is well known that the dominant frequency of oscillations in the solar photosphere is 3 mHz, which is the result of global resonant modes pertaining to the whole stella…
