Elemental Stoichiometry as an Ecological Biosignature with Applications to Life Detection

Pilar C. Vergeli, Cole Mathis, John F. Malloy +5

The vast chemical space of possible small molecules, estimated at 10^60 compounds for molecules composed of just C, N, O, and S, is only sparsely occupied by biology. We propose th…

The Influence of Stellar Phosphorus On Our Understanding of Exoplanets and Astrobiology

Natalie R. Hinkel, Hilairy E. Hartnett, Patrick A. Young

When searching for exoplanets and ultimately considering their habitability, it is necessary to consider the planet's composition, geophysical processes, and geochemical cycles in…

Exogeoscience and Its Role in Characterizing Exoplanet Habitability and the Detectability of Life

Cayman T. Unterborn, Paul K. Byrne, Ariel D. Anbar +24

The search for exoplanetary life must encompass the complex geological processes reflected in an exoplanet's atmosphere, or we risk reporting false positive and false negative dete…

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…

Detectability of Life Using Oxygen on Pelagic Planets and Water Worlds

Donald M Glaser, Hilairy Ellen Hartnett, Steven J. Desch +13

The search for life on exoplanets is one of the grand scientific challenges of our time. The strategy to date has been to find (e.g., through transit surveys like Kepler) Earth-lik…

An Interdisciplinary Perspective on Elements in Astrobiology: From Stars to Planets to Life

Natalie Hinkel, Hilairy Hartnett, Carey Lisse +1

Stellar elemental abundances direct impact planetary interior structure and mineralogy, surface composition, and life. However, the different communities that are necessary for pla…

Reconstructing Extreme Space Weather from Planet Hosting Stars

V. S. Airapetian, V. Adibekyan, M. Ansdell +80

The field of exoplanetary science is making rapid progress both in statistical studies of exoplanet properties as well as in individual characterization. As space missions provide…

Protoplanetary Disk Science Enabled by Extremely Large Telescopes

Hannah Jang-Condell, Sean Brittain, Alycia Weinberger +36

The processes that transform gas and dust in circumstellar disks into diverse exoplanets remain poorly understood. One key pathway is to study exoplanets as they form in their youn…

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…

Exploring Extreme Space Weather Factors of Exoplanetary Habitability

V. S. Airapetian, V. Adibekyan, M. Ansdell +46

It is currently unknown how common life is on exoplanets, or how long planets can remain viable for life. To date, we have a superficial notion of habitability, a necessary first s…

Geoscience and the Search for Life Beyond the Solar System

Rory Barnes, Anat Shahar, Cayman Unterborn +11

How can scientists conclude with high confidence that an exoplanet hosts life? As telescopes come on line over the next 20 years that can directly observe photons from terrestrial…

A procedure for observing rocky exoplanets to maximize the likelihood that atmospheric oxygen will be a biosignature

Steven J. Desch, Stephen Kane, Carey M. Lisse +3

Here we advocate an observational strategy to help prioritize exoplanet observations. It starts with more easily obtained observational data, and ranks exoplanets for more difficul…

Life Beyond the Solar System: Remotely Detectable Biosignatures

Shawn Domagal-Goldman, Nancy Y. Kiang, Niki Parenteau +38

For the first time in human history, we will soon be able to apply the scientific method to the question "Are We Alone?" The rapid advance of exoplanet discovery, planetary systems…

Exoplanet Biosignatures: A Review of Remotely Detectable Signs of Life

Edward W. Schwieterman, Nancy Y. Kiang, Mary N. Parenteau +15

In the coming years and decades, advanced space- and ground-based observatories will allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially habitab…
