Description

Zeeman Doppler imaging is the only observational method capable of providing spatially resolved maps of stellar magnetic fields. This technique is routinely used to reconstruct magnetic field topologies in different types of active stars. Recently ZDI of cool stars was improved to include a more realistic treatment of the polarised radiative transfer and a self-consistent modelling of the temperature and magnetic structures. In some cases these methodological extensions led to a major revision of ZDI maps. In this talk I will summarise basic principles of different versions of ZDI and discuss key limitations and ambiguities of this technique.
