Climates of Terrestrial Exoplanets and Biosignatures
Siddharth Bhatnagar, Emeline Bolmont, Nikita J. Boeren +18
Understanding the climates of terrestrial exoplanets and the detectability of biosignatures is an inherently interdisciplinary challenge, requiring the integration of insights from…
Detecting Atmospheric CO2 Trends as Population-Level Signatures for Long-Term Stable Water Oceans and Biotic Activity on Temperate Terrestrial Exoplanets
Janina Hansen, Daniel Angerhausen, Sascha P. Quanz +6
Identifying key observables is essential for enhancing our knowledge of exoplanet habitability and biospheres, as well as improving future mission capabilities. While currently cha…
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…
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…
