Large Fabry-Perot Interferometers are used in a variety of astronomical instrumentation, including spectro-polarimeters for 4-meter class solar telescopes. In this work we comprehe…
Flare Forecasting Algorithms Based on High-Gradient Polarity Inversion Lines in Active Regions
Domenico Cicogna, Francesco Berrilli, Daniele Calchetti +6
Solar flares emanate from solar active regions hosting complex and strong bipolar magnetic fluxes. Estimating the probability of an active region to flare and defining reliable pre…
Chromospheric Heating by Acoustic Waves Compared to Radiative Cooling: II -- Revised Grid of Models
Vahid Abbasvand, Michal Sobotka, Petr Heinzel +4
Acoustic and magnetoacoustic waves are considered to be possible agents of chromospheric heating. We present a comparison of deposited acoustic energy flux with total integrated ra…
Speckle statistics in adaptive optics images at visible wavelengths
Marco Stangalini, Fernando Pedichini, Enrico Pinna +11
Residual speckles in adaptive optics (AO) images represent a well-known limitation on the achievement of the contrast needed for faint source detection. Speckles in AO imagery can…
A Probabilistic Approach to the Drag-Based Model
Gianluca Napoletano, Roberta Forte, Dario Del Moro +3
The forecast of the time of arrival of a coronal mass ejection (CME) to Earth is of critical importance for our high-technology society and for any future manned exploration of the…
Occurrence and persistence of magnetic elements in the quiet Sun
