The true masses of radial-velocity exoplanets constrained by stability
Xander Byrne, Amy Bonsor
Exoplanets discovered with the radial velocity method suffer from a mass-inclination degeneracy: only the minimum mass is measured. An exoplanet with an Ea…

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…
