Researchers investigate the lighter side of Earth’s inner core
Researchers report in a new study that a carbon compound called iron carbide, combined with small amounts of silicon impurities, may be an important component of the inner core. The researchers performed computer simulations to model how an iron and nickel core containing either iron carbide, or iron carbide with some silicon, compares to the density and other known characteristics of the inner core.
