Habitability Models for Planetary Sciences

open access: yes, 2020
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades to study the habitability of Earth from local to global scales. Astrobiologists have been proposing different habitability models for some time, with little integration and ...

Determining Habitability: Which exoEarths should we search for life? [PDF]

open access: yes, 2010
Within the next few years, the first Earth-mass planets will be discovered around other stars. Some of those worlds will certainly lie within the classical "habitable zone" of their parent stars, and we will quickly move from knowing of no exoEarths to ...

Effects of Extreme Obliquity Variations on the Habitability of Exoplanets [PDF]

open access: yes, 2014
We explore the impact of obliquity variations on planetary habitability in hypothetical systems with high mutual inclination. We show that large amplitude, high frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo ...

Exploring and Validating Exoplanet Atmospheric Retrievals with Solar System Analog Observations

open access: yesThe Planetary Science Journal, 2023
Solar system observations that serve as analogs for exoplanet remote sensing data can provide important opportunities to validate ideas and models related to exoplanet environments.

RAPID WATER LOSS CAN EXTEND THE LIFETIME OF PLANETARY HABITABILITY [PDF]

open access: yes, 2015
Two habitable planetary states are proposed: an aqua planet like the Earth and a land planet that has a small amount of water. Land planets keep liquid water under larger solar radiation compared to aqua planets. Water loss may change an aqua planet into

Uncertainty Quantification in Planetary Thermal History Models: Implications for Hypotheses Discrimination and Habitability Modeling [PDF]

open access: yesAstrophysical Journal, 2019
Multiple hypotheses/models have been put forward regarding Earth’s cooling history. Searching for life beyond Earth has brought these models into a new light as they connect to an energy source that life can tap.
