Understanding HWO's Field of Regard and Characterization Requirement Trade Space with a Dynamic Observation Scheduling Algorithm

Corey Spohn, Christopher C. Stark, Dmitry Savransky +1

The Habitable Worlds Observatory (HWO) aims to image and characterize at least 25 ExoEarth candidates (EECs). Achieving this goal requires a detailed understanding of the observato…

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…

Habitable Worlds Observatory (HWO): Living Worlds Community Working Group: The Search for Life on Potentially Habitable Exoplanets

Giada Arney, Niki Parenteau, Natalie Hinkel +25

The discovery of a biosphere on another planet would transform how we view ourselves, and our planet Earth, in relation to the rest of the cosmos. We now know Earth is one planet a…

Determining the Detectability of H2O with Photometric Observations using Bayesian Analysis for Remote Biosignature Identification on exoEarths (BARBIE)

Natasha Latouf, Chris Stark, Avi Mandell +1

We examine the detectability of water (H2O) in the reflected-light spectrum of an Earth-like exoplanet assuming a photometric observational approach rather than spectroscopic. By q…

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…

Paths to Robust Exoplanet Science Yield Margin for the Habitable Worlds Observatory

Christopher C. Stark, Bertrand Mennesson, Steve Bryson +11

The Habitable Worlds Observatory (HWO) will seek to detect and characterize potentially Earth-like planets around other stars. To ensure that the mission achieves the Astro2020 Dec…
