The Sun cubE onE (SEE) is a 12U CubeSat mission proposed for a phase A/B study to the Italian Space Agency that will investigate Gamma and X-ray fluxes and ultraviolet (UV) solar e…
Total Solar Irradiance during the Last Five Centuries
V. Penza, F. Berrilli, L. Bertello +3
The total solar irradiance (TSI) varies on timescales of minute to centuries. On short timescales it varies due to the superposition of intensity fluctuations produced by turbulent…
The exoplanetary magnetosphere extension in Sun-like stars based on the solar wind -- solar UV relation
Raffaele Reda, Luca Giovannelli, Tommaso Alberti +6
The Earth's magnetosphere extension is controlled by the solar activity level via solar wind properties. Understanding such a relation in the Solar System is important for predicti…
Prediction of sunspot and plage coverage for Solar Cycle 25
Valentina Penza, Francesco Berrilli, Luca Bertello +2
Solar variability occurs over a broad range of spatial and temporal scales, from the Sun's brightening over its lifetime to the fluctuations commonly associated with magnetic activ…
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…
A novel approach to identify resonant MHD wave modes in solar pores and sunspot umbrae: analysis
M. Stangalini, D. B. Jess, G. Verth +12
The umbral regions of sunspots and pores in the solar photosphere are generally dominated by ~mHz oscillations, which are due to -modes penetrating the magnetic region. In th…
A New Method for Detecting Solar Atmospheric Gravity Waves
Daniele Calchetti, Stuart M. Jefferies, Bernhard Fleck +2
Internal gravity waves have been observed in the Earth's atmosphere and oceans, on Mars and Jupiter, and in the Sun's atmosphere. Despite ample evidence for the existence of propag…
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…
