What can the sun tell us about stellar activity?
Abstract
The solar-stellar connection relates high-resolution synoptic solar observations to observations of magnetic activity in stars with different rotation rates and internal structures. Our knowledge of magnetic fields in stellar convection zones is based on detailed observations of field structures in the Sun but recent measurements of magnetic activity in other late-type stars have extended our understanding of the solar dynamo. These observations have stimulated detailed modelling of processes associated with magnetic activity. Modulation of activity cycles in slowly rotating stars can be inferred from terrestrial data extending over the last 104 years, while the evolution of the Sun's magnetic field can be inferred from the behaviour of younger stars.
