Potential field extrapolation of the large-scale field topologies derived with ZDI from our SPIRou Stokes IVQU observations of AU Mic (left panel) and EV Lac (right panel). Open field lines are shown in blue and closed field lines in white. The color scale indicates the value of the radial field at the surface of the star (in G), as derived by ZDI. The stars are shown as viewed from the Earth at rotational phases 0.20 and 0.90, respectively, with the source surface arbitrarily set to 5 R_★. Animated movies are available online.
