  abstract = {{T}he physical properties of iron ({F}e) at high pressure and high temperature are crucial for understanding the chemical composition, evolution, and dynamics of planetary interiors. {I}ndeed, the inner structures of the telluric planets all share a similar layered nature: a central metallic core composed mostly of iron, surrounded by a silicate mantle, and a thin, chemically differentiated crust. {T}o date, most studies of iron have focused on the hexagonal closed packed (hcp, or epsilon) phase, as epsilon-{F}e is likely stable across the pressure and temperature conditions of {E}arth's core. {H}owever, at the more moderate pressures characteristic of the cores of smaller planetary bodies, such as the {M}oon, {M}ercury, or {M}ars, iron takes on a face-centered cubic (fcc, or gamma) structure. {H}ere we present compressional and shear wave sound velocity and density measurements of gamma-{F}e at high pressures and high temperatures, which are needed to develop accurate seismic models of planetary interiors. {O}ur results indicate that the seismic velocities proposed for the {M}oon's inner core by a recent reanalysis of {A}pollo seismic data are well below those of gamma-{F}e. {O}ur dataset thus provides strong constraints to seismic models of the lunar core and cores of small telluric planets. {T}his allows us to propose a direct compositional and velocity model for the {M}oon's core.},
