    • An alternative model for the presence of hot Jupiters contends that they were dynamically scattered to small orbital distances, where tidal effects circularized their orbits (33). If that process is in fact dominant over the type 2 migration model considered here, then these models need to be reconsidered. During the very high-eccentricity phase, it is likely that the giant planet could remove most of the terrestrial mass in the system, leaving little remaining to form planets.

    • 24 g); Earth is about 0.1% water by mass. Although we did not account for water loss during impacts, water contents of these simulated planets are more than an order of magnitude higher than in previous simulations (19). Thus, although the water contents listed in Table 1 are upper limits, the very high values are real.
