A parametric avoidance model based on stellar age, metallicity, and multiplicity excludes ~50% of 1.74M Gaia DR3 stars as poor candidates for complex life, retaining 777835 targets and releasing the catalog publicly.
Early Venus experienced large seasonal and latitudinal insolation redistribution but only modest orbit-averaged flux changes, making atmospheric opacity the dominant control on surface temperature rather than orbital forcing.
Young M dwarf flares exert greater chemical stress on primordial exo-Earth atmospheres than previous models, with potential for lasting changes in mixing ratios especially for low-abundance species.
Simulations using occurrence rates rank HWO ExEP stars by probability of hosting a temperate terrestrial planet or moon, reaching up to 50% for some systems.
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.
Mars provides a real-world case study of processes like volatile loss, climate evolution, and magnetism that determine habitability on small rocky planets at the edge of habitable conditions.
The HAges catalog compiles published asteroseismic and gyrochronological ages for 659 HWO target stars, finding that only ~5% have asteroseismic ages and ~20% have gyrochronal ages.
The paper reviews physical processes, modeling techniques, retrieval methods, and observational strategies for characterizing exoplanet atmospheres, emphasizing Swiss research progress.
