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…
Modeling Decadal and Centennial Solar UV Irradiance Changes
Raffaele Reda, Valentina Penza, Serena Criscuoli +5
Reconstructions of solar spectral irradiance - especially in the ultraviolet (UV) range - are crucial for understanding Earth's climate system. Although total solar irradiance (TSI…
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…
Reconstruction of the Total Solar Irradiance during the last Millenium
Valentina Penza, Luca Bertello, Matteo Cantoresi +5
Solar irradiance variations across various timescales, from minutes to centuries, represents a potential natural driver of past regional and global climate cold phases. To accurate…
