The Validation of the Top Targets for Atmospheric Characterization with JWST Discovered by TESS
Abstract
JWST has revolutionized our ability to characterize the atmospheres of exoplanets. We present a validation of ~70 planet candidates discovered by TESS that rank among the most promising targets for atmospheric characterization with JWST. These planet candidates were selected for validation based on their transmission or emission spectroscopy metric (TSM and ESM, respectively) compared to all planets and planet candidates listed on NASA's Exoplanet Archive. We only considered targets whose predicted secondary eclipse and transmission spectrum signal size would be observable by JWST at a 3-sigma level. We vetted each planet candidate using the software DAVE as well as all available photometric and spectroscopic ground-based follow up to rule out false positive scenarios. Each candidate was then validated using a combination of the VESPA and TRICERATOPS statistical validation softwares, including only targets with a false positive probability of less than 1%. We present these best-in-class targets for atmospheric characterization with JWST alongside all confirmed planets in bins of planetary radius and equilibrium temperature, ranked by TSM and ESM. This best-in-class list will serve as a guide for future exoplanet atmosphere observing campaigns with JWST and other space-based and ground-based telescopes.
