Caption: Figure 7.

Complex spin state of the secondary at the moment of secondary fission using the bi-lobed secondary fission model with νs = 0.5 for Moshup simulations. The horizontal bars indicate the values of the secondary’s moments of inertia. The spin states cluster about the intermediate axis, indicating non-principal axis rotation at the time of fission. The dynamic inertia is normalized by the mass-equivalent sphere inertia and the effective spin period is normalized by 2.33 hr, the disruption period of a 2 g cm−3 object.
