Isosurfaces of constant mass fractions at t ≈ 9000 s for models H15-1deg (left) and H15-2deg (right). The mass fractions are 7% for ⁵⁶Ni (blue) and 3% for ¹⁶O+²⁰Ne+²⁴Mg (red) and ¹²C (green). The morphology is almost identical to that shown in the lower left panel of Fig. 2 in HJM10, except for some additional small-scale structures in the better resolved model. There are two pronounced nickel plumes (blue) visible on the right, which travel at velocities up to 3800 km s^-1 and 4200 km s^-1 in model H15-2deg and H15-1deg, respectively, and two smaller nickel fingers on the left.
