  "abstract": "We perform molecular dynamics (MD) simulations of AlTi metallic alloy melts, with a specific focus on surface properties and the effect of oxygen. The simulations use a machine-learned inter- action potential (MLIP) that has recently been tested through experimental data for the statical and dynamical properties of AlTi melts in the bulk [Kato et al. (2026)]. We find that the surface- tension response to oxygen depends strongly on the AlTi composition. Element-resolved density profiles show that oxygen enrichment near the interface is accompanied by a suppression of the Al surface segregation observed in the oxygen-free liquid. The results are compared to experimental values obtained using levitation techniques in microgravity.",
