Update on interior structure models
• New thermodynamic model for liquid-Fe-S alloys: Terasaki 2019
-
agrees well with published and new low and high pressure dataMars models require significant more S than formation/compositional models
• New bulk composition model of Mars: Yoshizaki 2020
- based on data from Martian meteorites and spacecraft
- does not assume C1 composition for refractory lithophile elements
less iron in the mantle affects core composition and mantle moment of inertia
• Effect on Mars core structure and composition
