This study uses first-principles molecular dynamics simulations to investigate the carbon content in Earth's core. By analyzing density and compressional wave velocity of liquid iron-carbon alloys, the researchers find that a carbon content of 0.3-2.0 wt.% in the outer core satisfies both seismological observations and density constraints. This suggests the outer core could be the largest terrestrial carbon reservoir.
