Flares and variability in DS Tucanae A e AU Mic. The study: “Short-term variability of DS Tucanae A observed with TESS” of S. Colombo (INAF – OAPA) recently appeared on A&A
Stars are variable sources over timescales which depend on the phenomena triggering this variability. These phenomena are typically produced by the interaction between the stellar magnetic field and its plasma. Typical examples, observed and studied in great details in the Sun, are: flares (sudden release of a large amount of energy by the magnetic field which heats the gas in
