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…
X-ray Emission of Nearby Low-mass and Sun-like Stars with Directly Imageable Habitable Zones
Breanna A. Binder, Sarah Peacock, Edward W. Schwieterman +5
Stellar X-ray and UV radiation can significantly affect the survival, composition, and long-term evolution of the atmospheres of planets in or near their host star's habitable zone…
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…
