Asteroseismology is a powerful technique to infer the properties of stars by studying their oscillations. The recent dedicated space-borne missions CoRoT and Kepler have revolutionized the field with their unprecedented amount and quality of data. One of the major discovery was the first detection of a stellar cycle within the oscillations of a star. I will present this result and the properties of stellar oscillations in presence of a strong magnetic field.
