The Sun and Sun-like stars exhibit the intrinsic magnetic field that is maintained via the dynamo action working in the stellar interior. The stellar magnetic field is known to affect the long-term evolution of the star itself and the surrounding planets. Currently, observation of stellar magnetic activity is strongly limited or impossible in principle, which prevents the further understanding of stellar magnetic activity and its evolution. Based on the solar observation that allows the detailed investigation of magnetic activity, I am theoretically investigating the solar/stellar magnetic activities via numerical simulation.In particular, I aim to quantitatively characterize the stellar magnetic activity once the stellar fundamental parameters are given.
