Did Earth eat its leftovers? Impact ejecta as a component of the late veneer
Philip J. Carter, Sarah T. Stewart
The presence of highly siderophile elements in Earth's mantle indicates that a small percentage of Earth's mass was delivered after the last giant impact in a stage of 'late accret…
Atmosphere Loss in Oblique Super-Earth Impacts
Thomas R. Denman, Zoe M. Leinhardt, Philip J. Carter
Using smoothed particle hydrodynamics we model giant impacts of Super-Earth mass rocky planets between an atmosphere-less projectile and an atmosphere-rich target. In this work we…
Colliding in the shadows of giants: Planetesimal collisions during the growth and migration of gas giants
Philip J. Carter, Sarah T. Stewart
Giant planet migration is an important phenomenon in the evolution of planetary systems. Recent works have shown that giant planet growth and migration can shape the asteroid belt,…
Atmosphere loss in planet-planet collisions
Thomas R. Denman, Zoe M. Leinhardt, Phil J. Carter +1
Many of the planets discovered by the Kepler satellite are close orbiting Super-Earths or Mini-Neptunes. Such objects exhibit a wide spread of densities for similar masses. One pos…
Are exoplanetesimals differentiated?
Amy Bonsor, Philip J. Carter, Mark Hollands +3
Metals observed in the atmospheres of white dwarfs suggest that many have recently accreted planetary bodies. In some cases, the compositions observed suggest the accretion of mate…
The energy budgets of giant impacts
Philip J Carter, Simon J Lock, Sarah T Stewart
Giant impacts dominate the final stages of terrestrial planet formation and set the configuration and compositions of the final system of planets. A giant impact is believed to be…
Collisional stripping of planetary crusts
Philip J. Carter, Zoë M. Leinhardt, Tim Elliott +2
Geochemical studies of planetary accretion and evolution have invoked various degrees of collisional erosion to explain differences in bulk composition between planets and chondrit…
Hiding in the Shadows II: Collisional Dust as Exoplanet Markers
Jack Dobinson, Zoe M. Leinhardt, Stefan Lines +3
Observations of the youngest planets (1-10 Myr for a transitional disk) will increase the accuracy of our planet formation models. Unfortunately, observations of such planets…
Compositional evolution during rocky protoplanet accretion
Philip J. Carter, Zoë M. Leinhardt, Tim Elliott +2
The Earth appears non-chondritic in its abundances of refractory lithophile elements, posing a significant problem for our understanding of its formation and evolution. It has been…
Modelling circumbinary protoplanetary disks: I. Fluid simulations of the Kepler-16 and 34 systems
S. Lines, Z. M. Leinhardt, C. Baruteau +2
The Kepler mission's discovery of a number of circumbinary planets orbiting close (a_p < 1.1 au) to the stellar binary raises questions as to how these planets could have formed gi…
Numerically Predicted Indirect Signatures of Terrestrial Planet Formation
Zoë M. Leinhardt, Jack Dobinson, Philip J. Carter +1
The intermediate phases of planet formation are not directly observable due to lack of emission from planetesimals. Planet formation is, however, a dynamically active process resul…
A Collisional Origin to Earth's Non-chondritic Composition?
Amy Bonsor, Zoë M. Leinhardt, Philip J. Carter +3
Several lines of evidence indicate a non-chondritic composition for Bulk Earth. If Earth formed from the accretion of chondritic material, its non-chondritic composition, in partic…
