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 "…
Radiogenic Heating and its Influence on Rocky Planet Dynamos and Habitability
Francis Nimmo, Joel Primack, Sandra M. Faber +2
The thermal evolution of rocky planets on geological timescales (Gyr) depends on the heat input from the long-lived radiogenic elements potassium, thorium, and uranium. Concentrati…
Inclination damping on Callisto
Brynna G. Downey, Francis Nimmo, Isamu Matsuyama
Callisto is thought to possess a subsurface ocean, which will dissipate energy due to obliquity tides. This dissipation should have damped any primordial inclination within 1 Gyr -…
