The advent of radial velocity (RV) and transit photometry method has resulted in the
detection of more than 5000 exoplanets since 1995. Of these detected planets, a significant …

The current goals of the astrobiology community are focused on developing a framework for
the detection of biosignatures, or evidence thereof, on objects inside and outside of our solar …

Rocky planet compositions regulate planetary evolution by affecting core sizes, mantle
properties, and melting behaviors. Yet, quantitative treatments of this aspect of exoplanet …

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 …

We hypothesize that differences in the temperatures at which the rocky material condensed
out of the nebula gas can lead to differences in the composition of key rocky species (eg Fe …

From core to atmosphere, the oxidation states of elements in a planet shape its character.
Oxygen fugacity () is one parameter indicating these likely oxidation states. The ongoing …

Ocean-vaporizing impacts of chemically reduced planetesimals onto the early Earth have
been suggested to catalyze atmospheric production of reduced nitrogen compounds and …

ABSTRACT A major goal in the discovery and characterization of exoplanets is to identify
terrestrial-type worlds that are similar to (or otherwise distinct from) our Earth. Recent results …

Abstract The Transiting Exoplanet Survey Satellite mission was designed to find transiting
planets around bright, nearby stars. Here, we present the detection and mass measurement …

White dwarfs that have accreted planetary materials provide a powerful tool to probe the
interiors and formation of exoplanets. In particular, the high Fe/Si ratio of some white dwarf …
