Reconstructed maps of the large-scale field of GJ 876 in 2019 (top) and 2020 (bottom). The left, middle and right columns represent the radial, azimuthal, and meridional field components in spherical coordinates. The color bar is expressed in Gauss. The maps are shown in a flattened polar projection down to latitude –60◦ with the pole at the center and the equator depicted as a bold line. Outer ticks indicate phases of observations, assuming a rotation period of 83.7 d. -- astro-ph.EP
