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…
Artificial Greenhouse Gases as Exoplanet Technosignatures
Edward W. Schwieterman, Thomas J. Fauchez, Jacob Haqq-Misra +6
Atmospheric pollutants such as CFCs and NO have been proposed as potential remotely detectable atmospheric technosignature gases. Here we investigate the potential for artifi…
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…
An Overview of Exoplanet Biosignatures
Edward W. Schwieterman, Michaela Leung
This chapter reviews proposed exoplanet biosignatures, including their biological origins, observable features, atmospheric sinks, and potentially confounding abiotic sources. Emph…
The Impact of Extended HO Cross-Sections on Temperate Anoxic Planet Atmospheres: Implications for Spectral Characterization of Habitable Worlds
Wynter Broussard, Edward W. Schwieterman, Sukrit Ranjan +3
JWST has created a new era of terrestrial exoplanet atmospheric characterization, and with it the possibility to detect potential biosignature gases like CH. Our interpretati…
The effect of lightning on the atmospheric chemistry of exoplanets and potential biosignatures
Patrick Barth, Eva E. Stüeken, Christiane Helling +2
Lightning has been suggested to play a role in triggering the occurrence of bio-ready chemical species. Future missions (PLATO, ARIEL, HWO, LIFE) and ground-based ELTs will investi…
Modeling Atmospheric Lines By the Exoplanet Community (MALBEC) version 1.0: A CUISINES radiative transfer intercomparison project
Geronimo L. Villanueva, Thomas J. Fauchez, Vincent Kofman +15
Radiative transfer (RT) models are critical in the interpretation of exoplanetary spectra, in simulating exoplanet climates and when designing the specifications of future flagship…
Large Interferometer For Exoplanets (LIFE): XII. The Detectability of Capstone Biosignatures in the Mid-Infrared -- Sniffing Exoplanetary Laughing Gas and Methylated Halogens
Daniel Angerhausen, Daria Pidhorodetska, Michaela Leung +6
This study aims to identify exemplary science cases for observing NO, CHCl, and CHBr in exoplanet atmospheres at abundances consistent with biogenic production using a…
Giant Outer Transiting Exoplanet Mass (GOT 'EM) Survey. IV. Long-term Doppler Spectroscopy for 11 Stars Thought to Host Cool Giant Exoplanets
Paul A. Dalba, Stephen R. Kane, Howard Isaacson +29
Discovering and characterizing exoplanets at the outer edge of the transit method's sensitivity has proven challenging owing to geometric biases and the practical difficulties asso…
