Figure 5. Comparison of the physical properties of liquid and hcp-iron calculated along an isentropic temperature profile (T_ICB = 5882 K) with the PREM⁷² and reference data⁹⁵ (T_ICB = 6000 K).

(a) Calculated isentropic temperature profile started from 5882 K at 328.9 GPa for liquid and hcp-iron compared with the reference data⁹⁵ (b) Calculated adiabatic bulk modulus along adiabats for solid and liquid iron. (c) Calculated density along the 5882 K isentrope. (d) Calculated P-wave velocity along the isentrope.
