Characterizing the oxidation state of rocky exoplanets with the Large Interferometer for Exoplanets (LIFE)
Lorenzo Cesario, Tim Lichtenberg, Michiel Min +5
The paper evaluates the capability of the proposed LIFE space-based mid-infrared nulling interferometer to detect redox‑sensitive gases in Earth‑sized exoplanet atmospheres and the…
Detecting habitable exoplanet atmospheres with LIFE, the Large Interferometer for Exoplanets
Sarah Rugheimer, Aiden Weatherbee, James Fecanin +21
A key goal of astronomers with the next generation telescopes is to detect signs of life in exoplanet atmospheres. NASA's next flagship is the Habitable Worlds Observatory (HWO). I…
The exozodi spectral effect: Residual habitable zone dust may bias exoEarth characterization
Miles H. Currie, Christopher C. Stark, Eleonora Alei +1
The paper studies how residual exozodiacal dust in the habitable zones of nearby stars can add a continuum signal to direct imaging spectra of Earth-like exoplanets, potentially re…
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-…
Habitable Worlds Observatory Living Worlds Working Group: Surface Biosignatures on Potentially Habitable Exoplanets
Niki Parenteau, Anna Grace Ulses, Connor Metz +16
The Habitable Worlds Observatory (HWO) is the first NASA Astrophysics flagship mission with a key science goal of searching for signs of life on rocky habitable exoplanets beyond o…
A comprehensive spectroscopic reference of the solar system and its application to exoplanet direct imaging
Allison Payne, Geronimo L. Villanueva, Vincent Kofman +5
We present a calibrated database of reflectance spectra for the solar system planets (i.e., Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) and for Titan, spanning f…
