摘要:
Magnetic fields play an important role at all stages of stellar evolution, In Sun-like stars, they are generated in the outer convective layers. Studying the large-scale magnetic fields of these stars enlightens our understanding of the field properties and gives us observational constraints for the field generation models. In this review. 1 summarise the current observational picture of the large-scale magnetic fields of Sun-like stars, in particular solar-twins and planet host stars. I will discuss the observations of large-scale magnetic cycles, and compare these to the solar cycle.
