	abstract = {Seismic measurements made on Mars indicate that the liquid iron-nickel core is rich in light elements; however, the effects of these light components on the elasticity of Mars\&$\#$039; core remain poorly constrained. Here, we calculate elastic properties of various liquid Fe-X (X = Ni, S, C, O and H) mixtures using ab initio molecular dynamics simulations. We find that, at martian core conditions, the addition of S and O most effectively decreases the density of liquid iron, followed by C and H, while Ni has a minimal effect. As for compressional sound velocity (Vp), C increases Vp of liquid Fe throughout Mars\&$\#$039; core, while both S and O reduce Vp, the intensity of which diminishes with increasing pressure. Assuming a martian core made of a binary mixture, the seismically-inferred density would require the presence of at least 30 wt\% S.},
