An Investigation of Libration Heating and the Thermal State of Enceladus's Ice Shell
Wencheng D. Shao, Francis Nimmo
Tidal dissipation is thought to be responsible for the observed high heat loss on Enceladus. Forced librations can enhance tidal dissipation in the ice shell, but how such libratio…
Was Venus Ever Habitable? Constraints from a Coupled Interior-Atmosphere-Redox Evolution Model
Joshua Krissansen-Totton, Jonathan J. Fortney, Francis Nimmo
Venus's past climate evolution is uncertain. General circulation model simulations permit a habitable climate as late as ~0.7 Ga, and there is suggestive-albeit inconclusive-eviden…
Nucleosynthetic Pt isotope anomalies and the Hf-W chronology of core formation in inner and outer solar system planetesimals
Fridolin Spitzer, Christoph Burkhardt, Francis Nimmo +1
The 182Hf-182W chronology of iron meteorites provides crucial information on the timescales of accretion and differentiation of some of the oldest planetesimals of the Solar System…
Oxygen False Positives on Habitable Zone Planets Around Sun-Like Stars
Joshua Krissansen-Totton, Jonathan J. Fortney, Francis Nimmo +1
Oxygen is a promising exoplanet biosignature due to the evolutionary advantage conferred by harnessing starlight for photosynthesis, and the apparent low likelihood of maintaining…
Persephone: A Pluto-System Orbiter and Kuiper Belt Explorer
Carly Howett, Stuart Robbins, Bryan J. Holler +40
Persephone is a NASA concept mission study that addresses key questions raised by New Horizons' encounters with Kuiper Belt objects (KBOs), with arguably the most important being "…
