Extended Data Fig. 5 | Two-dimensional snapshots of a merger between
the proto-Jupiter with a 17M⊕ core and a 1M⊕ impactor. a, Density
contours in the orbital plane before the impact; b, before the impactor

arriving at the core; c, after the merger with the core; d, at about 10  h

after the impact. Time in each panel is measured since the start of the

simulation.
