Dependence of internal properties on compositional models for Mars. Top panel shows polar moment of inertia C/M r 2 for each of seven models, characterized by their fraction of core mass to total planetary mass M c /M p . Bottom panel shows core radius as a fraction of planetary radius for each compositional model. Horizontal lines in upper panel are upper limit for C/M r 2 (Esposito et al. 1992) and its recently determined value from the Mars Reconnaissance Orbiter mission (Konopliv et al. 2011)
