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…
