Science-Driven Performance Requirements for UV Coronagraph Design: Implications for O Detection in Earth-like Atmospheres
Amber V. Young, Giada Arney, Shawn Domagal-Goldman +6
Detecting biosignatures on Earth-like exoplanets from the Proterozoic era requires instrumentation capable of probing near-ultraviolet (NUV) spectral features, particularly ozone (…
ESCAPE: a small explorer mission to study the stellar drivers of exoplanet evolution
Allison Youngblood, Kevin France, Brian Fleming +37
The long-term stability of exoplanetary atmospheres depends critically on the extreme-ultraviolet (EUV) photon and high-energy particle fluxes from the host star, which are poorly…
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…
Multi-bandpass Photometry for Exoplanet Atmosphere Reconnaissance (MPEAR) with the Habitable Worlds Observatory (HWO) -- I. Differentiating Earth from Neptunes During Discovery
Eleonora Alei, Avi M. Mandell, Miles H. Currie +7
As the architecture for the Habitable Worlds Observatory (HWO) is being developed, it is crucial to optimize the observing strategies for a survey to detect and characterize Earth-…
Wavelength Requirements for Life Detection via Reflected Light Spectroscopy of Rocky Exoplanets
Joshua Krissansen-Totton, Anna Grace Ulses, Maxwell Frissell +21
Searching for signs of life is a primary goal of the Habitable Worlds Observatory (HWO). However, merely detecting oxygen, methane, or other widely discussed biosignatures is insuf…
Modern Earth-like Chemical Disequilibrium Biosignatures Are Challenging To Constrain Through Spectroscopic Retrievals
Amber Young, Tyler Robinson, Joshua Krissansen-Totton +4
Robust exoplanet characterization studies are underway, and the community is looking ahead toward developing observational strategies to search for life beyond our solar system. Wi…
The CUISINES Framework for Conducting Exoplanet Model Intercomparison Projects, Version 1.0
Linda E. Sohl, Thomas J. Fauchez, Shawn Domagal-Goldman +10
As JWST begins to return observations, it is more important than ever that exoplanet climate models can consistently and correctly predict the observability of exoplanets, retrieva…
Optimized Bandpasses for the Habitable Worlds Observatory's ExoEarth Survey
Christopher C. Stark, Natasha Latouf, Avi M. Mandell +1
A primary scientific goal of the future Habitable Worlds Observatory will be the direct detection and characterization of Earth-like planets. Estimates of the exoplanet yields for…
Inner Edge Habitable Zone Limits Around Main Sequence Stars: Cloudy Estimates
James D. Windsor, Tyler D. Robinson, Ravi kumar Kopparapu +3
Understanding the limits of rocky planet habitability is one of the key goals of current and future exoplanet characterization efforts. An intrinsic concept of rocky planet habitab…
Bayesian Analysis for Remote Biosignature Identification on exoEarths (BARBIE) II: Using Grid-Based Nested Sampling in Coronagraphy Observation Simulations for O2 and O3
Natasha Latouf, Avi Mandell, Geronimo Villanueva +8
We present the results for the detectability of the O2 and O3 molecular species in the atmosphere of an Earth-like planet using reflected light at the visible wavelengths. By quant…
Retrievals Applied To A Decision Tree Framework Can Characterize Earth-like Exoplanet Analogs
Amber V. Young, Jaime Crouse, Giada Arney +3
Exoplanet characterization missions planned for the future will soon enable searches for life beyond our solar system. Critical to the search will be the development of life detect…
Inferring Chemical Disequilibrium Biosignatures for Proterozoic Earth-Like Exoplanets
Amber V. Young, Tyler D. Robinson, Joshua Krissansen-Totton +9
Chemical disequilibrium quantified via available free energy has previously been proposed as a potential biosignature. However, exoplanet biosignature remote sensing work has not y…
