Structural properties of Fe‐27 wt % S and Fe‐17 wt % Si liquid alloys at high pressure and high temperature (0–5 GPa/1400–2300 K) are measured by synchrotron X‐ray diffraction. Sulfur strongly modifies the local structure of liquid iron whereas silicon has only small structural effects. Fe‐27 wt % S melts are indeed poorly ordered which explains a higher compressibility compared to pure liquid Fe. These results point out the necessity to consider the strong effect of S on liquid Fe properties while modeling planetary interiors. They imply a low S content in the Earth's outer core, leaving Si as a strong candidate, and argue for a present‐day Martian solid core when combined with previous global chemical models.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380285711830685836","@type":"Researcher","foaf:name":[{"@value":"C.
