Extended Data Fig. 4 | The change of internal energy caused by the
merger between the proto-Jupiter with a 10M⊕ rock/ice core and a
10 M⊕ impactor. a, The enclosed internal energy Einternal of Jupiter before
and after the impact as a function of radius. b, The net change of enclosed
internal energy ΔEinternal of Jupiter as a function of radius.
