Recent advances in X-ray spectroscopy from Chandra and XMM-Newton combined with Zeeman-Doppler imaging have shed new light on the structure of magnetic loops on cool stars. These results have overturned our view of stellar coronae and forced us to rethink the way we model the magnetic fields of solar-like stars. The high emission measure and low rotational modulation of the X-ray emission from these stars was originally thought to be due to their extended coronae. New observations of high coronal densities however suggest a more compact filamented structure. Modelling of coronal loops based on surface Zeeman-Doppler images confirms this picture showing emission mainly from high latitudes. This talk will review recent advances in understanding the structure and energetics of magnetic loops on cool stars and will compare these with our current understanding of the solar corona.
