Considering contact forces during the formation of planetesimals by gravitational collapse: mutual orbits, spin states, and shapes
Jackson T. Barnes, Stephen R. Schwartz, Seth A. Jacobson
In this work, we apply a soft-sphere discrete element method (SSDEM) within the PKDGRAV N-body integrator to investigate the formation of planetesimal systems through the gravitati…
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…
Impact Induced Atmosphere-Mantle Exchange Sets the Volatile Elemental Ratios on Primitive Earths
Howard Chen, Seth A. Jacobson
Conventional planet formation theory suggests that chondritic materials have delivered crucial atmospheric and hydrospheric elements such as carbon (C), nitrogen (N), and hydrogen…
Stochastic accretion of the Earth
Paolo A. Sossi, Ingo L. Stotz, Seth A. Jacobson +2
Earth is depleted in volatile elements relative to chondritic meteorites, its possible building blocks. The extent of this depletion increases with decreasing condensation temperat…
Predictions for the Dynamical States of the Didymos System before and after the Planned DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +33
NASA's Double Asteroid Redirection Test (DART) spacecraft is planned to impact the natural satellite of (65803) Didymos, Dimorphos, around 23:14 UTC on 26 September 2022, causing a…
Highly siderophile elements were stripped from Earth's mantle by iron sulfide segregation
David C. Rubie, Vera Laurenz, Seth A. Jacobson +4
Highly siderophile elements (HSEs) are strongly depleted in the bulk silicate Earth (BSE) but are present in near-chondritic relative abundances. The conventional explanation is th…
