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…
Near-equilibrium isotope fractionation during planetesimal evaporation
E. D. Young, A. Shahar, F. Nimmo +4
Silicon and Mg in differentiated rocky bodies exhibit heavy isotope enrichments that have been attributed to evaporation of partially or entirely molten planetesimals. We evaluate…
Reorientation of Sputnik Planitia implies a Subsurface Ocean on Pluto
F. Nimmo, D. P. Hamilton, W. B. McKinnon P. M. Schenk +60
The deep nitrogen-covered Sputnik Planitia (SP; informal name) basin on Pluto is located very close to the longitude of Pluto's tidal axis[1] and may be an impact feature [2], by a…
Convection in a volatile nitrogen-ice-rich layer drives Pluto's geological vigor
William B. McKinnon, Francis Nimmo, Teresa Wong +61
The vast, deep, volatile-ice-filled basin informally named Sputnik Planum is central to Pluto's geological activity[1,2]. Composed of molecular nitrogen, methane, and carbon monoxi…
Formation of Charon's Red Poles From Seasonally Cold-Trapped Volatiles
W. M. Grundy, D. P. Cruikshank, G. R. Gladstone +38
A unique feature of Pluto's large satellite Charon is its dark red northern polar cap. Similar colours on Pluto's surface have been attributed to organic macromolecules produced by…
