Plausible planetesimal structures resulting from a range of redox and disruption scenarios. Redox-sensitive results indicate that relatively small cores form for most bulk compositions above IW, but core sizes can change dramatically between −3 ≤ ΔIW ≤ 0. Disruption can produce additional scenarios that are either Fe- or silicate-rich, depending on the details of the events. Mantle stripping can lead to bodies with larger CMFs as well as bodies formed from mixed fragments (Asphaug & Reufer 2014).
