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…
