A Gap in the Densities of Small Planets Orbiting M Dwarfs: Rigorous Statistical Confirmation Using the Open-source Code RhoPop
J. G. Schulze, Ji Wang, J. A. Johnson +4
Using mass-radius-composition models, small planets () are typically classified into three types: iron-rich, nominally Earth-like, and those…
Fizzy Super-Earths: Impacts of Magma Composition on the Bulk Density and Structure of Lava Worlds
Kiersten M. Boley, Wendy R. Panero, Cayman T. Unterborn +3
Lava worlds are a potential emerging population of Super-Earths that are on close-in orbits around their host stars with likely partially molten mantles. To date, few studies addre…
The Nominal Range of Rocky Planet Masses, Radii, Surface Gravities and Bulk Densities
Cayman T. Unterborn, Steven J. Desch, Jonas Haldemann +4
The two primary observable quantities of an exoplanet--its mass and radius--alone are not sufficient to probe a rocky exoplanet's interior composition and mineralogy. To overcome t…
A Reanalysis of the Composition of K2-106b: an Ultra-short Period Super-Mercury Candidate
Romy Rodríguez Martínez, B. Scott Gaudi, Joseph G. Schulze +9
We present a reanalysis of the K2-106 transiting planetary system, with a focus on the composition of K2-106b, an ultra-short period, super-Mercury candidate. We globally model exi…
Detecting Biosignatures in the Atmospheres of Gas Dwarf Planets with the James Webb Space Telescope
Caprice Phillips, Ji Wang, Sarah Kendrew +5
Exoplanets with radii between those of Earth and Neptune have stronger surface gravity than Earth, and can retain a sizable hydrogen-dominated atmosphere. In contrast to gas giant…
Analytic Estimates of the Achievable Precision on the Physical Properties of Transiting Planets Using Purely Empirical Measurements
Romy Rodriguez Martinez, Daniel J. Stevens, B. Scott Gaudi +4
We present analytic estimates of the fractional uncertainties on the mass, radius, surface gravity, and density of a transiting planet, using only empirical or semi-empirical measu…
On the Probability that a Rocky Planet's Composition Reflects its Host Star
J. G. Schulze, Ji Wang, J. A. Johnson +3
The bulk density of a planet, as measured by mass and radius, is a result of planet structure and composition. Relative proportions of iron core, rocky mantle, and gaseous envelope…
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…
The Pressure and Temperature Limits of Likely Rocky Exoplanets
Cayman T. Unterborn, Wendy R. Panero
The interior composition of exoplanets is not observable, limiting our direct knowledge of their structure, composition, and dynamics. Recently described observational trends sugge…
Stellar Chemical Clues As To The Rarity of Exoplanetary Tectonics
Cayman T. Unterborn, Scott D. Hull, Lars P. Stixrude +3
Earth's tectonic processes regulate the formation of continental crust, control its unique deep water and carbon cycles, and are vital to its surface habitability. A major driver o…
Effects of Mg/Si on Exoplanetary Refractory Oxygen Budget
Cayman T. Unterborn, Wendy R. Panero
Solar photospheric abundances of refractory elements mirror the Earth's to within ~10 mol% when normalized to the dominant terrestrial planet-forming elements Mg, Si and Fe. This a…
Scaling the Earth: A Sensitivity Analysis of Terrestrial Exoplanetary Interior Models
Cayman T. Unterborn, Evan E. Dismukes, Wendy R. Panero
An exoplanet's structure and composition are first-order controls of the planet's habitability. We explore which aspects of bulk terrestrial planet composition and interior structu…
Thorium Abundances in Solar Twins and Analogues: Implications for the Habitability of Extrasolar Planetary Systems
Cayman T. Unterborn, Jennifer A. Johnson, Wendy R. Panero
We present the first investigation of Th abundances in Solar twins and analogues to understand the possible range of this radioactive element and its effect on rocky planet interio…
The Role of Carbon in Extrasolar Planetary Geodynamics and Habitability
Cayman T. Unterborn, Jason E. Kabbes, Jeffrey S. Pigott +2
The proportions of oxygen, carbon and major rock-forming elements (e.g. Mg, Fe, Si) determine a planet's dominant mineralogy. Variation in a planet's mineralogy subsequently affect…
