Chemistry, Climate, and Transmission Spectra of TRAPPIST-1 e Explored with a Multimodel Sparse Sampled Ensemble
Eric T. Wolf, Edward W. Schwieterman, Jacob Haqq-Misra +6
TRAPPIST-1 e is one of a few habitable zone exoplanets that is amenable to characterization in the near term. In this study our motivations are both scientific and technical. Our t…
Examining the Potential for Methyl Halide Accumulation and Detectability in Possible Hycean-Type Atmospheres
Michaela Leung, Shang-Min Tsai, Edward W Schwieterman +2
Some sub-Neptune planets may host habitable conditions; for example "Hycean" worlds with H2 envelopes over liquid water oceans can maintain potentially hospitable pressures and tem…
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…
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…
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…
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…
The Importance of the Upper Atmosphere to CO/O Runaway on Habitable Planets Orbiting Low-Mass Stars
Sukrit Ranjan, Edward W. Schwieterman, Michaela Leung +2
Efforts to spectrally characterize the atmospheric compositions of temperate terrestrial exoplanets orbiting M-dwarf stars with the James Webb Space Telescope (JWST) are now underw…
