The Efficient Delivery Of Highly-siderophile Elements To The Core Creates A Mass Accretion Catastrophe For The Earth
The excess abundance of highly siderophile elements (HSEs), as inferred for the terrestrial planets and the Moon, is thought to record a `late veneer’ of impacts after the giant impact […]

The Distribution Of Impactor Core Material During Large Impacts On Earth-like Planets
Large impacts onto young rocky planets may transform their compositions, creating highly reducing conditions at their surfaces and reintroducing highly siderophile metals to their mantles. Key to these processes is […]
