Hidden magnetic fields in stellar interiors probed by asteroseismology

Understanding the distribution and evolution of angular momentum is crucial for comprehending star formation processes, stellar evolution and activity, and their influence on planet formation and environment. Recent space photometry missions, such as CoRoT and Kepler, have revolutionized our understanding of stellar structure and evolution by highlighting discrepancies in current angular momentum transport models. However, incorporating magnetic fields into these models could offer a solution to this transport problem. Even though detecting and measuring magnetic fields within stellar interiors utilizing perturbative methods through asteroseismology is a recent breakthrough, there remains a need for a non-perturbative model, of which the first steps of the development will be presented in this poster. This model would comprehensively consider both stellar rotation and magnetic fields in a two-dimensional framework, testing the existing perturbative methods, surpassing their limitations and tackling the area of strong and complex internal magnetic fields.
