Observational Tests of Terrestrial Planet Buffering Feedbacks and the Habitable Zone Concept
Morgan Underwood, Adrian Lenardic, Johnny Seales +1
The habitable zone is defined as the orbital region around a star where planetary feedback cycles buffer atmospheric greenhouse gases that, in combination with solar luminosity, ma…
Internal or external magma oceans in the earliest protoplanets -- perspectives from nitrogen and carbon fractionation
Damanveer S. Grewal, Johnny D. Seales, Rajdeep Dasgupta
When the extent of protoplanetary melting approached magma ocean (MO)-like conditions, alloy melts efficiently segregated from the silicates to form metallic cores. The nature of t…
The Temporal Onset of Habitability For Earth-Like Planets
Johnny Seales, Adrian Lenardic
The ability of a planet to maintain surface water, key to life as we know it, depends on solar and planetary energy. As a star ages, it delivers more energy to a planet. As a plane…
A Note on Planet Size and Cooling Rate
Johnny Seales, Adrian Lenardic
Variation in the balance of forces that drive and resist tectonic plate motions allows small terrestrial planet to cooler slower than larger ones. Given that interior cooling affec…
Layered Uncertainty in Planetary Thermal History Models: Implications for Hypotheses Discrimination and Habitability Modeling
Johnny Seales, Adrian Lenardic
Multiple hypotheses/models have been put forward regarding the cooling history of the Earth. The search for life beyond Earth has brought these models into a new light as they conn…
Assessing the Intrinsic Uncertainty and Structural Stability of Planetary Models: 1) Parameterized Thermal-Tectonic History Models
Johnny Seales, Adrian Lenardic, William Moore
Thermal history models, that have been used to understand the geological history of Earth, are now being coupled to climate models to map conditions that allow planets to maintain…
Deep Water Cycling and Delayed Onset Cooling of the Earth
Johnny Seales, Adrian Lenardic
Changes that occur on our planet can be tracked back to one of two energy sources: the sun and the Earth's internal energy. The motion of tectonic plates, volcanism, mountain build…
Different is More: The Value of Finding an Inhabited Planet that is Far From Earth 2.0
Adrian Lenardic, Johnny Seales
The search for an inhabited planet, other than our own, is a driver of planetary exploration in our solar system and beyond. Using information from our own planet to inform search…
