The Solirad (So) as a Convenient Unit for Quoting Astronomical Irradiances for Planetary Insolations and Exoplanetary Instellations
Eric E. Mamajek, Jason T. Wright, Noah W. Tuchow +3
Measurements of physical parameters for stars and (exo)planets are often quoted in units normalized to the Sun and/or Earth. The nominal total solar irradiance, ${S}^{\rm N}_{\odot…
Bioverse: Assessing the Ability of Direct Imaging Surveys to Empirically Constrain the Habitable Zone via Trends in Albedo
Noah W. Tuchow, Christopher C. Stark, Daniel Apai +2
Will future direct imaging missions such as NASA's upcoming Habitable Worlds Observatory (HWO) be able to understand Earth-sized planets as a population? In this study, we simulate…
A Terminology and Quantitative Framework for Assessing the Habitability of Solar System and Extraterrestrial Worlds
Daniel Apai, Rory Barnes, Matthew M. Murphy +13
The search for extraterrestrial life in the Solar System and beyond is a key science driver in astrobiology, planetary science, and astrophysics. A critical step is the identificat…
HZ_evolution: A Package to Calculate Habitable Histories
Noah W. Tuchow, Jason T. Wright
We present HZ_evolution, a Python package to characterize the habitable histories of exoplanets. Given inputs of a planet's current effective flux and host star properties, HZ_evol…
SPORES-HWO. II. Companion Mass Limits and Updated Planet Properties for 120 Future Exoplanet Imaging Targets from 35 yr of Precise Doppler Monitoring
Caleb K. Harada, Courtney D. Dressing, Emma V. Turtelboom +17
A goal of the future Habitable Worlds Observatory (HWO) is to directly image and spectroscopically characterize true Earth-analogs. However, if a large fraction of HWO target stars…
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…
HPIC: The Habitable Worlds Observatory Preliminary Input Catalog
Noah Tuchow, Chris Stark, Eric Mamajek
The Habitable Worlds Observatory Preliminary Input Catalog (HPIC) is a list of ~13,000 nearby bright stars that will be potential targets for the Habitable Worlds Observatory (HWO)…
The Abundance of Belatedly Habitable Planets and Ambiguities in Definitions of the Continuously Habitable Zone
Noah W. Tuchow, Jason T. Wright
A planet's history dictates its current potential to host habitable conditions and life. The concept of the Continuously Habitable Zone (CHZ) has been used to define the region aro…
Potential Habitability as a Stellar Property: Effects of Model Uncertainties and Measurement Precision
Noah Tuchow, Jason Wright
Knowledge of a star's evolutionary history combined with estimates of planet occurrence rates allows one to infer its relative quality as a location in the search for biosignatures…
A Framework for Relative Biosignature Yields from Future Direct Imaging Missions
Noah W. Tuchow, Jason T. Wright
Future exoplanet direct imaging missions, such as HabEx and LUVOIR, will select target stars to maximize the number of Earth-like exoplanets that can have their atmospheric composi…
