Significant progress has been made recently in our understanding of the structure of stellar magnetic fields, thanks to advances in detection methods such as Zeeman–Doppler Imaging. The extrapolation of this surface magnetic field into the corona has provided three‐dimensional models of the coronal magnetic field and plasma. This method is sensitive mainly to the magnetic field in the bright regions...
