Figure 4

Pressure-temperature conditions reached, estimated from radiation hydrodynamics simulations with Sesame EOS 7171. Triangular points show where plastic structure remained after either a single shock (blue) or double shock (green), while the red points indicate shots where plastic structure disappeared. For comparison, the conditions at which diamond was observed to form from CH in20 are shown by black crosses. The Hugoniot lines indicate conditions reached by a single shock in CH2, calculated either by SESAME or DFT simulations23. Conditions estimated from different models of planetary interiors - thermal boundary layer (TBL)37, water-only7 and icy Uranus35 - are shown as dotted lines.
