Exploring the Diverse Outcomes of Large Asteroid Impacts During the Era of Terrestrial Planet Formation
The most dramatic phases of terrestrial planet formation are thought to be oligarchic and chaotic growth, on timescales of up to 100-200 Myr, when violent impacts occur between large planetesimals […]
