Comparisons of the core and mantle compositions of earth analogs from different terrestrial planet formation scenarios
Jesse T. Gu, Rebecca A. Fischer, Matthew C. Brennan +5
The chemical compositions of Earth's core and mantle provide insight into the processes that led to their formation. N-body simulations, on the other hand, generally do not contain…
Nonlinearity of the post-spinel transition and its expression in slabs and plumes worldwide
Junjie Dong, Rebecca A. Fischer, Lars Stixrude +6
At the interface of Earth's upper and lower mantle, the post-spinel transition boundary controls the dynamics and morphologies of downwelling slabs and upwelling plumes, and its Cl…
Water storage capacity of the Martian mantle through time
Junjie Dong, Rebecca A. Fischer, Lars P. Stixrude +3
Water has been stored in the Martian mantle since its formation, primarily in nominally anhydrous minerals. The short-lived early hydrosphere and intermittently flowing water on th…
Geophysical Evolution During Rocky Planet Formation
Tim Lichtenberg, Laura K. Schaefer, Miki Nakajima +1
Progressive astronomical characterization of planet-forming disks and rocky exoplanets highlight the need for increasing interdisciplinary efforts to understand the birth and life…
Constraints on terrestrial planet formation timescales and equilibration processes in the Grand Tack scenario from Hf-W isotopic evolution
Nicholas G. Zube, Francis Nimmo, Rebecca Fischer +1
We examine 141 N-body simulations of terrestrial planet late-stage accretion that use the Grand Tack scenario, coupling the collisional results with a hafnium-tungsten (Hf-W) isoto…
Redox evolution via gravitational differentiation on low mass planets: implications for abiotic oxygen, water loss and habitability
R. Wordsworth, L. Schaefer, R. Fischer
The oxidation of rocky planet surfaces and atmospheres, which arises from the twin forces of stellar nucleosynthesis and gravitational differentiation, is a universal process of ke…
