Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The Habitable Worlds Observatory (HWO) is a future NASA flagship mission concept identified by the Astro2020 Decadal Survey as the highest priority for large space missions. HWO sh…
Callisto from JWST: CO2-rich terrain on the leading hemisphere and global patterns of H2O ice
Maria Camarca, Katherine de Kleer, Richard J. Cartwright +5
We present maps of H2O, CO2, and a 4.57 um spectral feature across Callisto's surface observed using the James Webb Space Telescope (JWST). H2O ice was mapped by measuring band par…
Tracing the source of carbon oxides on the large moons of Uranus
Richard J. Cartwright, Sasha Cryan, Rosario Brunetto +15
The Uranian moons Ariel, Umbriel, Titania, and Oberon are enriched in CO2 mixed with CO, but the origin(s) of these carbon oxides, be they primarily native or radiolytic, remains u…
Retrieving the Red Edge on Earth-like Planets with Heterogeneous Clouds and Surfaces
Zachary Burr, Mario Damiano, Vincent Kofman +2
The detection and characterization of potentially habitable exoplanets is one of the chief goals of astrophysics for the coming decades. Imaging in reflected light is well suited f…
Bayesian Analysis for Remote Biosignature Identification on exoEarths (BARBIE) IV: Analyzing CO2 Detections in the Near-IR to Determine the Long-Wavelength Cut-off for the Habitable Worlds Observatory Coronagraph
Celeste Hagee, Natasha Latouf, Avi M. Mandell +3
We present our analysis of how the detectability of carbon dioxide (CO2) on an Earth-like planet varies with respect to signal-to-noise ratio (SNR), wavelength, and molecular abund…
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-…
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…
From Global Climate Models (GCMs) to Exoplanet Spectra with the Global Emission Spectra (GlobES)
Thomas J. Fauchez, Geronimo L. Villanueva, Vincent Kofman +2
In the quest to understand the climates and atmospheres of exoplanets, 3D global climate models (GCMs) have become indispensable. The ability of GCMs to predict atmospheric conditi…
Assessing Ocean World Habitability with HWO
Richard J. Cartwright, Lynnae Quick, Marc Neveu +5
The instrument payload of the future Habitable Worlds Observatory (HWO) will span a wide range of wavelengths, including the ultraviolet (UV) region that cannot be easily accessed…
Bayesian Analysis for Remote Biosignature Identification on exoEarths (BARBIE) \RNum{3}: Introducing the KEN
Natasha Latouf, Michael D. Himes, Avi M. Mandell +4
We deploy a newly-generated set of geometric albedo spectral grids to examine the detectability of methane (CH4) in the reflected-light spectrum of an Earth-like exoplanet at visib…
The pale blue dot: using the Planetary Spectrum Generator to simulate signals from hyper realistic exo-Earths
Vincent Kofman, Geronimo Villanueva, Thomas Fauchez +5
The atmospheres and surfaces of planets show tremendous amount of spatial variation, which has a direct effect on the spectrum of the object, even if this may not be spatially reso…
The VSPEC Collection: A suite of utilities to model spectroscopic phase curves of 3D exoplanet atmospheres in the presence of stellar variability
Ted M Johnson, Cameron Kelahan, Avi M. Mandell +5
We present the Variable Star PhasE Curve (VSPEC) Collection, a set of Python packages for simulating combined-light spectroscopic observations of 3-dimensional exoplanet atmosphere…
Detectability Simulations of a NIR Surface Biosignature on Proxima Centauri b with Future Space Observatories
Connor O. Metz, Nancy Y. Kiang, Geronimo L. Villanueva +2
Telescope missions are currently being designed which will make direct imaging of habitable exoplanets possible in the near future, and studies are needed to quantify the detectabi…
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…
