Simulations of terrestrial planet formation with giant planet scattering going on. Turns out that scattering is bad for the terrestrial planets. Prediction based on current knowledge of giant planet distribution is that terrestrials should be more common at ~0.3 AU than at 1 AU, and it looks like the solar system may be something of an unusual case as it combines a rich terrestrial planet system with low dust emission.

Simulations of the debris from the moon-forming impact. Combining this with detectability and observations of the frequency of stars with warm debris discs suggests that the fraction of stars that form terrestrial planets is less than ~10% under the model that formation of terrestrial planets goes through a giant impacts stage.
