Ultraviolet-Driven Atmospheric Degeneracies Challenge Conventional Biosignature Frameworks for Terrestrial Planets with Ultracool M Dwarf Hosts: An Archean-Analog TRAPPIST-1 e Case Study
Evan L. Sneed, Edward W. Schwieterman, Sarah R. Peacock +2
The ultraviolet (UV) spectrum of a host star strongly shapes the atmospheric composition and potential biosignatures of its planets. This relationship may be especially important f…
The Search for Technosignatures: a Review of Possibilities
Clément Vidal, Benji L. Fields, Damian R. Sowinski +19
This paper reviews the diverse range of technosignatures that have been proposed in the literature. We organize the review by spatial scales from the Earth and the solar system to…
Toward Inferring the Surface Fluxes of Biosignature Gases on Rocky Exoplanets from Telescope Spectra
Nicholas F. Wogan, Natasha E. Batalha, Joshua Krissansen-Totton +5
The James Webb Space Telescope and the future Habitable Worlds Observatory aim to discover exoplanet atmospheric spectra that detect life. Currently, most existing spectral "retrie…
Large Interferometer For Exoplanets (LIFE). XIV. Finding terrestrial protoplanets in the galactic neighborhood
Lorenzo Cesario, Tim Lichtenberg, Eleonora Alei +62
The increased brightness temperature of young rocky protoplanets during their magma ocean epoch makes them potentially amenable to atmospheric characterization to distances from th…
A Radio Technosignature Search of TRAPPIST-1 with the Allen Telescope Array
Nick Tusay, Sofia Z. Sheikh, Evan L. Sneed +6
Planet-planet occultations (PPOs) occur when one exoplanet occults another exoplanet in the same system as seen from the Earth's vantage point. PPOs may provide a unique opportunit…
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…
Developing a Drift Rate Distribution for Technosignature Searches of Exoplanets
Megan G. Li, Sofia Z. Sheikh, Christian Gilbertson +4
A stable-frequency transmitter with relative radial acceleration to a receiver will show a change in received frequency over time, known as a "drift rate''. For a transmission from…
