Imaging Venus-like Worlds: Spectral, Polarimetric, and UV Diagnostics for the Habitable Worlds Observatory
Stephen R. Kane, Kimberly M. Bott, Kenneth E. Goodis Gordon +15
Understanding planetary habitability requires a comparative approach that explores the divergent evolutionary outcomes of Earth and Venus. The Habitable Worlds Observatory (HWO) wi…
Giant Outer Transiting Exoplanet Mass (GOT `EM) Survey. V. Two Giant Planets in Kepler-511 but Only One Ran Away
Yayaati Chachan, Paul A. Dalba, Daniel P. Thorngren +6
Systems hosting multiple giant planets are important laboratories for understanding planetary formation and migration processes. We present a nearly decade-long Doppler spectroscop…
The Impact of Extended CO Cross Sections on Temperate Anoxic Planet Atmospheres
Wynter Broussard, Edward W. Schwieterman, Clara Sousa-Silva +3
Our interpretation of terrestrial exoplanet atmospheric spectra will always be limited by the accuracy of the data we use as input in our forward and retrieval models. Ultraviolet…
History and Habitability of the LP 890-9 Planetary System
Rory Barnes, Laura N. R. do Amaral, Jessica Birky +42
We present numerous aspects of the evolution of the LP 890-9 (SPECULOOS-2/TOI-4306) planetary system, focusing on the likelihood that planet c can support life. We find that the ho…
The TESS-Keck Survey. XXII. A sub-Neptune Orbiting TOI-1437
Daria Pidhorodetska, Emily A. Gilbert, Stephen R. Kane +40
Exoplanet discoveries have revealed a dramatic diversity of planet sizes across a vast array of orbital architectures. Sub-Neptunes are of particular interest; due to their absence…
A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST
TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80
Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
