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 Hadean, once thought to be uninhabitable and tumultuous, has more recently been recontextualized as a clement time in which oceans, land, and life likely appeared on Earth. Thi…
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…
Alternative Methylated Biosignatures I: Methyl Bromide, A Capstone Biosignature
Michaela Leung, Edward W. Schwieterman, Mary N. Parenteau +1
The first potential exoplanet biosignature detections are likely to be ambiguous due to the potential for false positives: abiotic planetary processes that produce observables simi…
