A Bayesian, Process-Based Framework for Exoplanet Life Detection Under Uncertain Priors

To the point

Use a Bayesian framework to search for life on exoplanets by weighing how likely an observed signal is produced by living versus non-living processes, while also estimating how probable life is in that planet’s environment and how climate, geology, and evolutionary history shape those signals through diverse models and observations.

Exoplanet Biosignatures: Future Directions

We introduce a Bayesian method for guiding future directions for detection of life on exoplanets. We describe empirical and theoretical work necessary to place constraints on the relevant likelihoods, including those emerging from better ...
