While the existence of cycles in stellar chromospheric flux has been known for some time, the nature of the corresponding coronal response has been more elusive. We describe recent results on the relationship between cyclic variations in surface magnetic flux and coronal structure as observed in the rotational modulation and magnitude of the X-ray emission, the coronal density and the fraction of open magnetic flux. We re-assess the role of prominence observations in understanding the topology of stellar coronas and present a new paradigm for prominence support which allows for extended prominences to co-exist with a compact corona. We summarise the results of a multi-wavelength study of AB Dor combining Chandra observations with coronal field extrapolation based on Zeeman-Doppler images and consider the nature of possible cycles on this well-observed star.
