Oxygen False Positives on Habitable Zone Planets Around Sun‐Like Stars
AGU Advances, 2021 Oxygen is a promising exoplanet biosignature due to the evolutionary advantage conferred by harnessing starlight for photosynthesis, and the apparent low likelihood of maintaining oxygen‐rich atmospheres without life.

Simultaneous characterization of the atmospheres, surfaces, and exomoons of nearby rocky exoplanets
Earth and Planetary Physics, 2018 Atmospheric composition is an important indicator of habitability and life. The presence or absence of a large exomoon around an Earth-size exoplanet could have important consequences for planet climate stability.

Effect of the exoplanet magnetic field topology on its magnetospheric radio emission [PDF]
A&A, Forthcoming article, 2018, 2018 The magnetized wind from stars that impact exoplanets should lead to radio emissions. According to the scaling laws derived in the solar system, the radio emission should depend on the stellar wind, interplanetary magnetic field, and topology of the exoplanet magnetosphere. The aim of this study is to calculate the dissipated power and subsequent radio

A New Method For Studying Exoplanet Atmospheres Using Planetary Infrared Excess [PDF]
ApJL 898 L35 (2020), 2020 To date, the ability for observers to reveal the composition or thermal structure of an exoplanet's atmosphere has rested on two techniques: high-contrast direct imaging and time-series observations of transiting exoplanets. The former is currently limited to characterizing young, massive objects while the latter requires near 90 degree orbital ...
