Stellar magnetism, dynamo action and the solar-stellar connection

Solar-like stars are magnetic rotating objects that have a direct impact on their environment. Being able to understand the physical mechanisms behind such an intense magnetic activity is key. It is believe that dynamo action is the source of the magnetic field in solar-like stars and that there is a complex feedback loop between dynamo, rotation and braking by their wind along their secular evolution. By mean of high performance simulations we will discuss how such complex feedback loop comes about and summarise our current understanding of the magnetohydrodynamics of solar-like stars.
