A retrieval technique infers surface gas fluxes from exoplanet spectra via inversion of a photochemical-climate model, demonstrated on synthetic TRAPPIST-1 e data with an Archean-like biosphere.
Introduces a reflection spectroscopy metric and uses KELT-9 injection-recovery tests to demonstrate that rotational line broadening from rapid stellar rotation and large misalignments must be included when assessing detectability of exoplanet reflected spectra.
LIFE mission simulations show that baselines of 25-80 m or even discrete values can achieve planet yield and fringe tracking with less than 10% performance loss compared to wider ranges.
Joint radial-velocity analysis revises GJ 3378b's period to 21.45 days and minimum mass to 2.3 Earth masses, placing the habitable-zone planet near the cosmic shoreline.
