The efficient delivery of highly-siderophile elements to the core creates a mass accretion catastrophe for the Earth
Richard J. Anslow, Maylis Landeau, Amy Bonsor +2
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 im…
Constraining the survival of HCN during cometary impacts
Catriona H. McDonald, Amy Bonsor, Auriol S. P. Rae +3
Cometary impacts have been invoked as an atmosphere-independent method of stockpiling hydrogen cyanide (HCN), a key prebiotic feedstock molecule, into environments favourable for t…
The atmospheric entry of cometary impactors
Richard J Anslow, Amy Bonsor, Zoe R Todd +4
Cometary impacts play an important role in the early evolution of Earth, and other terrestrial exoplanets. Here, we present a numerical model for the interaction of weak, low-densi…
The plausibility of origins scenarios requiring two impactors
Richard J Anslow, Amy Bonsor, Paul B Rimmer +3
Hydrogen cyanide delivered by cometary impactors can be concentrated as ferrocyanide salts, which may support the initial stages of prebiotic chemistry on the early Earth. One way…
