The Barnard's Star Planetary System: Stability, Composition, and Evolution of Four Sub-Earth Exoplanets
Xander Byrne, Claire Marie Guimond, Amy Bonsor +3
Barnard's Star is the nearest single star to the Sun (1.8 pc), and hosts four recently-discovered planets. The star also has well-characterized stellar abundances of important rock…
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…
