The Venus Benchmark: Resolving Degeneracies in Terrestrial Exoplanet Spectra with DAVINCI
Stephen R. Kane, David S. Alexander, Shahid Aslam +8
The characterization of terrestrial exoplanets with thick, CO-dominated atmospheres via transmission and emission spectroscopy is limited by degeneracies between atmospheric co…
Imaging Venus-like Worlds: Spectral, Polarimetric, and UV Diagnostics for the Habitable Worlds Observatory
Stephen R. Kane, Kimberly M. Bott, Kenneth E. Goodis Gordon +15
Understanding planetary habitability requires a comparative approach that explores the divergent evolutionary outcomes of Earth and Venus. The Habitable Worlds Observatory (HWO) wi…
A WISPR of the Venus Surface: Analysis of the Venus Nightside Thermal Emission at Optical Wavelengths
J. Lustig-Yaeger, N. R. Izenberg, M. S. Gilmore +8
Parker Solar Probe (PSP) conducted several flybys of Venus while using Venus' gravity for orbital adjustments to enable its daring passes of the Sun. During these flybys, PSP turne…
Science opportunities with solar sailing smallsats
Slava G. Turyshev, Darren Garber, Louis D. Friedman +25
Recently, we witnessed how the synergy of small satellite technology and solar sailing propulsion enables new missions. Together, small satellites with lightweight instruments and…
Hierarchical Bayesian Atmospheric Retrieval Modeling for Population Studies of Exoplanet Atmospheres: A Case Study on the Habitable Zone
Jacob Lustig-Yaeger, Kristin S. Sotzen, Kevin B. Stevenson +5
With the growing number of spectroscopic observations and observational platforms capable of exoplanet atmospheric characterization, there is a growing need for analysis techniques…
Triton Haze Analogues: the Role of Carbon Monoxide in Haze Formation
Sarah E. Moran, Sarah M. Hörst, Chao He +7
Triton is the largest moon of the Neptune system and possesses a thin nitrogen atmosphere with trace amounts of carbon monoxide and methane, making it of similar composition to tha…
Retrieving Exoplanet Atmospheres using Planetary Infrared Excess: Prospects for the Nightside of WASP-43 b and other Hot Jupiters
Jacob Lustig-Yaeger, Kevin B. Stevenson, L. C. Mayorga +4
To increase the sample size of future atmospheric characterization efforts, we build on the planetary infrared excess (PIE) technique that has been proposed as a means to detect an…
On the Utility of Transmission Color Analysis I: Differentiating Super-Earths and Sub-Neptunes
Kristin S. Sotzen, Kevin B. Stevenson, Erin M. May +9
The majority of exoplanets found to date have been discovered via the transit method, and transmission spectroscopy represents the primary method of studying these distant worlds.…
Habitability Models for Astrobiology
Abel Méndez, Edgard E. Rivera-Valentín, Dirk Schulze-Makuch +31
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades…
Transmission Spectroscopy of the Earth-Sun System to Inform the Search for Extrasolar Life
L. C. Mayorga, J. Lustig-Yaeger, E. M. May +7
Upcoming NASA astrophysics missions such as the James Webb Space Telescope will search for signs of life on planets transiting nearby stars. Doing so will require co-adding dozens…
The Fundamental Connections Between the Solar System and Exoplanetary Science
Stephen R. Kane, Giada N. Arney, Paul K. Byrne +7
Over the past several decades, thousands of planets have been discovered outside of our Solar System. These planets exhibit enormous diversity, and their large numbers provide a st…
The Venus Life Equation
Noam R. Izenberg, Diana M. Gentry, David J. Smith +5
Ancient Venus and Earth may have been similar in crucial ways for the development of life, such as liquid water oceans, land-ocean interfaces, favorable chemical ingredients and en…
A Geologically Robust Procedure For Observing Rocky Exoplanets to Ensure that Detection of Atmospheric Oxygen is an Earth-Like Biosignature
Carey M. Lisse, Steven J. Desch, Cayman T. Unterborn +7
In the next decades, the astrobiological community will debate whether the first observations of oxygen in an exoplanets atmosphere signifies life, so it is critical to establis…
Solar System Ice Giants: Exoplanets in our Backyard
Abigail Rymer, Kathleen Mandt, Dana Hurley +110
Future remote sensing of exoplanets will be enhanced by a thorough investigation of our solar system Ice Giants (Neptune-size planets). What can the configuration of the magnetic f…
Exoplanet Diversity in the Era of Space-based Direct Imaging Missions
Ravi Kopparapu, Eric Hebrard, Rus Belikov +55
This whitepaper discusses the diversity of exoplanets that could be detected by future observations, so that comparative exoplanetology can be performed in the upcoming era of larg…
