On the Temporal Variability in the Magnetic Dichotomy of Late M Dwarf Stars
Giuseppina Nigro, Francesco Berrilli, Giuseppe Bono +4
Rapidly rotating late M dwarfs are observed in two different branches of magnetic activity, although they operate in the same stellar parameter range. Current empirical evidence in…
Investigating the Temperature Sensitivity of UV Line Ratios in the 280 nm Region of Solar-like Stars
Valentina Penza, Serena Criscuoli, Raffaele Reda +7
Stellar UV spectra are fundamental diagnostics of physical and magnetic properties of stars. For instance, lines like Mg II at 280 nm serve as valuable indicators of stellar activi…
A catalogue of observed geo-effective CME/ICME characteristics
R. Mugatwala, S. Chierichini, G. Francisco +7
One of the goals of Space Weather studies is to achieve a better understanding of impulsive phenomena, such as Coronal Mass Ejections (CMEs), in order to improve our ability to for…
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…
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…
Occurrence and persistence of magnetic elements in the quiet Sun
F. Giannattasio, F. Berrilli, G. Consolini +3
Turbulent convection efficiently transports energy up to the solar photosphere, but its multi-scale nature and dynamic properties are still not fully understood. Several works in t…
The dependence of the [FUV-MUV] colour on solar cycle
M. Lovric, F. Tosone, E. Pietropaolo +4
Solar UV variability is extremely relevant for the stratospheric ozone. It has an impact on Earth's atmospheric structure and dynamics through radiative heating and ozone photochem…
Chromospheric heating by acoustic waves compared to radiative cooling
M. Sobotka, P. Heinzel, M. Švanda +3
Acoustic and magnetoacoustic waves are among the possible candidate mechanisms that heat the upper layers of solar atmosphere. A weak chromospheric plage near a large solar pore NO…
N-body model of magnetic flux tubes reconnecting in the solar atmosphere
Luca Giovannelli, Francesco Berrilli, Dario Del Moro +7
The investigation of dynamics of the small scale magnetic field on the Sun photosphere is necessary to understand the physical processes occurring in the higher layers of solar atm…
Super-diffusion versus competitive advection: a simulation
D. Del Moro, F. Giannattasio, F. Berrilli +3
Magnetic element tracking is often used to study the transport and diffusion of the magnetic field on the solar photosphere. From the analysis of the displacement spectrum of these…
Magnetic pattern at supergranulation scale: the Void Size Distribution
Francesco Berrilli, Stefano Scardigli, Dario Del Moro
The large-scale magnetic pattern of the quiet sun is dominated by the magnetic network. This network, created by photospheric magnetic fields swept into convective downflows, delin…
Diffusion of magnetic elements in a supergranular cell
