Time evolution of both merger simulations until 6000 s for the equal-mass merger (top panels) and the unequal mass merger with a mass ratio of q = 0.7 (bottom panels). The rows show slices of density, magnetic field strength, and mass fraction of the material originally part of one of the white dwarfs in the mid-plane. Both mergers show a large amplification of the magnetic field. In the equal-mass merger, the merger remnant is almost fully mixed. In the unequal-mass merger, the centre of the merger remnant consists of the unmixed core of the initially more massive white dwarf.
