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…

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…

Venus as a Nearby Exoplanetary Laboratory

Stephen R. Kane, Giada Arney, Paul Byrne +9

The key goals of the astrobiology community are to identify environments beyond Earth that may be habitable, and to search for signs of life in those environments. A fundamental as…

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…

Venus as a Laboratory for Exoplanetary Science

Stephen R. Kane, Giada Arney, David Crisp +9

The current goals of the astrobiology community are focused on developing a framework for the detection of biosignatures, or evidence thereof, on objects inside and outside of our…
