[astro-ph.EP] Static retrieval frameworks are leading tools for interpreting exoplanet observations, yet time-independent modelling leaves them prone to degeneracy and unable to resolve exoplanets’ histories.

Machine Learning As A Transformative Tool for (Exo-)Planetary Science
The exploration of planetary bodies in our Solar system and beyond relies on the processing and interpretation of large, spatio-temporally inconsistent, and heterogeneous datasets.

Determining the Detectability of H2O With Photometric Observations Using Bayesian Analysis For Remote Biosignature Identification On exoEarths (BARBIE)
We examine the detectability of water (H2O) in the reflected-light spectrum of an Earth-like exoplanet assuming a photometric observational approach rather than spectroscopic.

Bayesian Analysis for Remote Biosignature Identification on exoEarths (BARBIE) III: Introducing the KEN
We deploy a newly-generated set of geometric albedo spectral grids to examine the detectability of methane (CH4) in the reflected-light spectrum of an Earth-like exoplanet at visible and near-infrared wavelengths […]
